Inverting Differentiator Lab
In this lab assignment, we examined the forced response of a circuit which performs a differentiation, which is the circuit output derivative with respect to time of the input to the circuit. We then applied sinusoids of various frequencies to the circuit and compare the output with our expectations based on analysis.
Picture of our pre-lab that determines the circuit output Vout as a function of the circuit input, Vin. The sinusoidal function we supplied is amplitude of 1 V, offset 0 and frequency 1kHz, 2kHz, and 500Hz.
Graph of frequency 1kHz Vout = 1.228V
Graph of frequency 500Hz Vout = 0.614V
The % error is then solve on this picture.
We measured the time difference between Vin and Vout using peak to peak method.
The time difference is 0.355 ms, then we can use it to calculate RC by applying to function Vout=RC dv/dt
