These significant aspects ultimately prove providing greater aid in developing the prevailing socio-political conditions by broader utilization of DSP (Department of Electrical and Computer Engineering, “The Broader Impact of DSP in a Global, Economic and Social Context”). V. THE IMPACT OF DSP IN A GLOBAL CONTEXT In relation to the global context, the component i.e. DSP has been able to create substantial impact in the form of introducing along with implementing pioneering technological advancements by a greater degree. It can be viewed that DSP has been able to provide end number of solutions. The primary solutions can be determined based upon the digitization and the upliftment of electronics to an improved level. This component has widely benefitted the global market in terms of assisting the worldwide organizations towards attaining their respective business targets. For instance, the company i.e. Texas Instruments Incorporated (TI) has been benefitted by the use of this component i.e. DSP at large. It can be viewed that the company has been running its sales operations in approximately 25 countries by employing around 43,000 employees in a worldwide basis. The various applications relating to DSP eventually made possible for the company towards performing its business activities worldwide in an effective manner (Department of Electrical and Computer Engineering, “The Broader Impact of DSP in a Global, Economic and Social Context”). DSP is broadly applied in building integrated circuits that are applied in electronic business domain. Taking this aspect into concern, an engineer named Jack Kilby was able to build the first integrated circuit in the year 1958 by utilizing the applications of DSP. This instance proved to be much successful with reference to the fact that the global semiconductor market was able to grow nearly about $132 billion in the year 1996. Following the rise in the worldwide semiconductor market, semiconductor contents along with electronics equipments have also been viewed to emerge in new business markets in most of the developing countries. Moreover, with broader application of DSP, the computer along with communication sector can also be viewed to develop their market position at large. The growth can be seen because of digitalization and it is anticipated that continual utilization of various applications of DSP can lead to higher rates of expansion, boosting the overall semiconductor trade with an expected long term growth of 15% to 20% in an annual basis (Department of Electrical and Computer Engineering, “The Broader Impact of DSP in a Global, Economic and Social Context”). With due analysis, it can be apparently viewed that the semiconductor domain especially in the equipment and the electronic segment has developed considerably owing to greater utilization of DSP based applications. Additionally, it can be viewed that around 15 million U.S. built traveler cars along with light convenience vehicles have been sold during the year 1996 in the United States, containing greater value of the semiconductor devices. Thus, considering all the aforesaid aspects, it can be affirmed that DSP has been able to impose extensive impact in the global context and is still continuing to perform the same (Texas instruments, “Impact on the Global Economy”). VI. HISTORY AND UTILIZATION OF DSP DSP, as mentioned in the earlier section is duly considered to be one of the widely utilized components in numerous business domains. The history of DSP dates back in the late 1980, when a CD player was used for making digital records for the first time. This instance came into play when a new historical trend belonging to the last half-century was set. The trend signified the creation of a strong substitute of analog signals by way of digital signals. Following this phase, DSP originally came into formation for the first time. The initial company which became quite successful in following various applications of DSP was Texas Instruments, which introduced the Speak & Spell toy in the year 1978. This product had various attractive features such as pronouncing different words while typing various keys in a keyboard. Although it looked like a child's toy, it contained a potent chip which processed digital signals. It was the first ever product which legitimately used the DSP technology (IEEE, “Digital Signal Processing”). The snapshot of the toy has been provided below. Source: (IEEE, “Digital Signal Processing”). Electrical signals tend to remain present everywhere as these signals are widely used in computers, communication systems, entertainment devices, measuring instruments and also in imaging devices. Such signals basically comprise two sorts of signals that include digital and analog. In this regard, digital signals are recognized as those signals that are controllable to a limited set of distinct values. The other sort of signal is analog signal, wherein signals are passed by way of continuous varying quantities. For instance, a telephone is often viewed to be using analog signals, since continual variance in pressure are associated with noise waves that are converted into constantly unstable voltages of an electrical indication. Computers, on the other hand, are often observed to be dealing with binary signals (IEEE, “Digital Signal Processing”). There are two valuable advantages of digital signals. Firstly, digital signals can be replicated in an exact manner. Secondly, digital signals can be widely utilized for conducting manipulation. In a clearer context, digital signals can be manipulated as per the requirements. These aspects make the component i.e. DSP much applicable in the overall context of information technology segment (IEEE, “Digital Signal Processing”). As already discussed in the above sections, DSP possesses numerous practical applications that can be effectively utilized for determining appropriate solutions. In this similar context, DSP can be efficiently exploited for the purpose of digitization of waveforms from both practical and theoretical perspective. This aspect can be duly considered as one of the imperative factors in determining the wide applicability of DSP in a global context. In a broader context, DSP can be utilized for complex nonlinear or linear algorithms. It can be affirmed that efficient utilization of DSP has made the process of fabrication quite easier. This component is highly utilized for industrial purposes and considering all these aspects, DSP is considered to be highly reliable. In addition, the DSP processors are applied for other purposes as well. It can be designed and optimized for the purpose of executing various DSP algorithms. Also, most of these processors contribute in supporting numeric, repetitive, intensive along with high performance tasks among others. Thus, all these broad applications of DSP make this component even more reliable (Murmu, “Application of Digital Signal Processing on Tms320c6713 Dsk”). VII. IMPACT OF THE DIGITAL REVOLUTION IN ACOUSTIC SIGNAL PROCESSING Digital Revolution is understood as a term, which is used for representing the change from electronic and analog mechanical technology to digital technology. This concept came into existence during the time period 1950s to 1970s. This particular aspect has been able to create mass impact, as it introduced digital record keeping systems along with digital computers that have created all round diversity in the technological edge. On the other hand, Acoustic Signal Processing is regarded as the process through which different forms of information are extracted by way of signals that are present in the solid earth and the atmosphere (University of Rhode Island, History of Computers”). It can be apparently observed that the notion of Digital Revolution imposed considerable impact upon the procedure of Acoustic Signal processing. This can be justified with reference to the fact that the accessibility of skillfully optimized processors of digital signal processing has given rise towards replacement of several bulky mechanical or electrical components with solid IC circuits in a variety of research and real-world applications. The programmability of such processors eventually contributed in making specific and simple algorithm based calculations, proving much beneficial for Acoustic Signal Processing by a certain degree. This vital aspect ensured appropriate running of this application on regular DSP platforms. Moreover, the aspect also proved to provide greater aid in determining the optimum utilization of DSP, impacting Acoustic Signal Processing in a uniformed manner. It can be viewed that several real-world applications have been effectively utilized, resulting in substituting mechanical/electronic elements in sound/vibration control, music synthesis, generation of melody hall sound effects in homes and echo cancellation in various recording studios among others (University of Rhode Island, History of Computers”). Considering all the aforementioned aspects, it can be summarized that the facet of Digital Revolution has been able to impose considerable impacts not only in the process of Acoustic Signal processing, but also in other relevant fields. The impacts can be measured in terms of diversifying the factors associated with sound control along with creation of various effects in mechanical/electronic fields. VIII. CONCLUSION From the overall analysis, it can be affirmed that the aspect of DSP and its various applications play a decisive role in developing the technological domain by a considerable level. In relation to this standpoint, the broader impacts of DSP in various fields such as socio-political, global along with economic contexts can be apparently observed. In relation to the economic context, the impact of DSP can be apparently observed in terms of developing better financial integration and assisting the organizations to advance their respective operational functions. From the viewpoint of socio-political perspective, the aspect of DSP and its numerous applications impose extensive impact through addressing along with mitigating various sorts of crisis situations. Apart from these, it can also be apparently observed that the aspect of Digital Revolution also imposed extensive impact upon Acoustic Signal Processing at large. The introduction of the ICs and the development of the modern processors significantly determine the importance of Digital Revolution over the aspect of Acoustic Signal Processing by a certain degree. It can be affirmed that the above discussed research provided with the opportunity of acquiring a brief idea about the applications of DSP and its impact upon several valuable areas such as economic, socio-political along with global context.
