Question

The goal of this project is to design, simulate, build and testa simple speaker system that can connect to a portable audio devicesuch as an mp3 player or laptop. The system has the followingrequirements:

§         Accept astandard head-phone audio jack as an input.

§         At leastone built-in speaker.

§         It mustprovide a means of controlling the volume continuously.

§         It mustalso have a means of controlling the treble (frequencies > 900Hz) or the bass (frequencies < 300 Hz).

Explanation / Answer

Hi Ted Follwoign the instructions in the problemLYou need to workfrom input level/impedance to output level/impedance. All thecomponents listed will do. The simplest way will be use opamps,with rc filters configured low and high. Basically you the ideas ofswitihes, circuitry, and the frequency trnsmittence throey to helpyou are. It is a thinking problem designed to mimic the complexcircuits seen in many engineering books. I will post something hereIf I can find something Good luck for now Good luck for now
