Electronics

A detailed Summary of Electronics


This project requires us to design and build a circuit that generates specified functions on the oscilloscope, as given on the project description. Also, we were required to design a means of selecting different frequencies and different amplitudes. This was especially difficult because the selection had to be made directly from the breadboard. For the final part of the lab, we were to draw the graphs we obtained to show how the various functions were generated digitally. The results we got were very sound. We were able to generate all of the minimum requirements (a square wave and ramp wave). Also, we were able to generate the waves that would give us extra credit (a triangle wave and approximations to a sine wave). We also discovered a way to easily vary frequency and amplitude.

This experiment uses four operational amplifiers (opamps) to deliver these waveforms in the 6 Hz to 7000 Hz range. The sine wave is a pseudo sine wave produces by a very simple wave

shaping circuit. A digital counter can be used along with a DAC to generate analog voltage functions of time such as square wave and ramp wave. In this lab, we were to design and build a circuit that generates an analog


constant which lowers the gradient of the ramp. The switching levels havenot changed so the frequency

Poor soldering is the most likely reason that the circuit
