Download file to see previous pages ASP applies analog circuit components like rheostats, capacitors, and transistors. ASP has been in use for numerous years. With the arrival of the digital processor and later microchip, DSP has turned into a more dominant approach for signal processing. ASP is founded on the natural capacity of the analog framework to decipher differential equations. This way, ASP defines a physical framework. Solutions for these equations can be acquired in real-time by using identical hardware to carry out a variety of signal processing protocols in DSP while designing a framework for every type of protocol in the core of ASP. Similar signal processing protocols can be repeated several times to produce the same outcomes while facing a parameter variation in ASP because of a difference in temperature or power supply.
Any time-uninterrupted signal with a time differing trait is a representation of another time differing measure in an analog signal. This signal is different from a digital one because of small, significant fluctuations that are evident in figure 1. This understanding of the analog signal is important for understanding the difference between ASP and DSP (Tektronix, 2001, p. 5). ASP largely occurs in an electrical setting but mechanical, air-filled, hydraulic, and other frameworks can transmit analog signals as well. An analog signal applies some feature of the channel to transmit the signal’s data. For instance, an aneroid barometer applies a rotational position as the signal for transmitting pressure data.
The feature most widely used in ASP is electric energy, then frequency, electric current, and charge. An analog signal might transmit any data. Such a signal is treated as a calculated response to variations in physical phenomena like sound, light, heat, location, and weight. To do this, a response by use of a transducer is required.  ...Download file to see next pages Read More

When we say analog the “ transmission uses signals that are exact replicas of a sound wave or picture being transmitted” ( thinkquest.org ). For example, a pattern of heartbeat is seen on the ECG machine which can be interpreted visually by a doctor. The original music sound is considered an analog. However, when it comes to encoding sound or music, the digital transmission is used nowadays. The main reason is explained by Smith ( 1999 ) in the book Why Digitize? Smith asserts that : .. flexibility is one of the...
