Project for Electronics Class (ECET 345)

Project Description

The objective of this project is to design, simulate and build a speech filter. The design should operate on less that ±6 Volts DC. Please keep in mind that you should monitor the cost of the design components. Therefore you will need to determine the frequency band of speech and investigate low power options for the design. After reviewing the various tradeoffs which happens after design and simulations, you should then order the parts for the actual design. Your design must include simulations (Multisim) as well as power and frequency analysis. Make sure your input signal has the various frequency ranges that demonstrates that your design works. You must also compare the actual simulation results to the actual results and explain any differences.

Your circuit should address the following:

1. Demonstrate the speech filter response of the design.

2. Power analysis of the design

3. What could you have done differently to make the circuit more efficient whether its cost, performance or simply a different design implementation?
