Engineering and Constructions Executive Summary - Essay Example

The input is first amplified and then converted to digital signal, before the signal is listened through the speaker it is converted back to analog. Circuit explanation The power supply section converts the alternating wave to a direct wave. A transformer, Rectifier Bridge and a voltage regulator are the main components of the power supply. A mixer mixes two signal and produce a mixed wave. A graphic equalizer has basically three sections; a splitter, filters and a combiner. Splitter splits a signal and filter filters a particular frequency.

Combiner combines the frequencies after filtration. Voltage and power amplifiers are utilized to enhance the power and quality of the signal. Circuit calculation Assumptions are made and values for mixer transistor, input, power supply, graphic equalizer, and voltage and power amplifiers are calculated to produce the circuit. Circuit test The calculated values are tested on the circuit and it is found that the calculated values have approximately same results on the circuit. Project cost The total cost of the components is almost $36.24. The industry partner cost is about $4800 and the total student cost is about $11200.

Review of Risks The risks involved in the utilization of electricity and other electric instruments could be minimized by following the rules and regulations of electric safety. Labs safety instructions must have an importance. The risk management strategy should be followed and in case a plan fails a second plan should be there. Wider Professional issues Project should be managed properly to finish the project in time. The project should be consulted with the industry partners to remain the project on track.

Research is made to verify that there is nothing that is not known considering the project. Control Procedures Scheduling of the project would be a better control procedure. Project should be divided into various parts and each part is scheduled accordingly. Conflicts will be minimized by considering all the options. A change strategy should be there and industry partners could impose any changes in the project. INTRODUCTION The word ‘Karaoke’ is taken from the Japanese language, where ‘kara’ and ‘oke’ are combined to drive the meaning of ‘karaoke’.

The word ‘kara’ means ‘blank’ and ‘oke’ is derived to term orchestra. In general, a machine that eliminates the lead vocalist from a song or a music video is known as karaoke machine. The karaoke machines were developed to provide a singer with the full orchestra. At places where there is a need of orchestra and it is impossible to provide a singer with the full orchestra, karaoke machines are utilized to fulfill the lacking of band or orchestra. Audio cassette tapes and video cassette tapes were employed by the early karaoke machines.

By the advancements in the technology, karaoke machines used compact disks, video compact disks and DVDs. Now a day the digital electronics revolutionized the technology and the basic structure of karaoke machine is changed as compared to its early version. The title of our project is “Transistor Level Implementation of Karaoke Machine with six-band Graphic Equalizer”. In the project our mission is to develop a karaoke machine with a six band equalizer. The karaoke machine is utilizing transistor instead of op-amps.

The circuitry is not a complex one. The concept of six band graphic equalizer has enhanced the division of frequency into its various
