ECE 336
Project 2
Due before the last class
Design, build, and evaluate a function generator that will generate a sinusoidal wave, a
triangular wave, and a square wave output, all within the frequency range of 100 Hz to 10
kHz. The amplitude of the each waveform should be able to vary from +0.1 to +5V.
Select
Op-Amps with sufficient SR.
Power supply voltages of +15V and -15V are to be used.
The report should contain a complete circuit diagram. The circuit diagram should show all
component values, device types and other relevant information. Experimental results
should be compared with theoretical values and PSICE simulations and the differences
should be discussed. The paper should contain all design analysis and relevant design
considerations. The experimental results (generated waveforms) must be dated and
confirmed by signature of one of the Graduate Teaching Assistants.
Please print a check-off sheet stating that you can obtain square waves at variable
magnitude (such as 0.5V and 5 V) and variable frequency (such as 500 Hz, 8 kHz), also
triangular wave and sinusoidal wave can be generated. It will be a good idea to attached
oscillographs of waveforms in the report.
The following is an example of possible waveform generation circuits.
