Day 21

In this lab assignment, we will be concerned with the steady-state response of electrical to sinusoidal input. the input and output signals both have the same frequency, but the two signals can have different amplitudes and phase angles.

in the pre-lab, we going to derive formula, and use it.

the circuit is set up with 2 10KOhm, 1 1uF capacitor, and a op amp. 

Vin and Vout with frequency 100Hz

Vin and Vout with frequency 1KHz 

Vin and Vout with frequency 5KHz 

summary table,  

final table with gain and phase under the different frequency.

In this lab, build a oscillator on EveryCircuit.

during the building circuit, we are going to build a 99Hz. We calculate theoretical value for the pot, which is 8371Ohm.

the circuit is set up.

the picture is about Vout, the frequency is 99.8, its percent different is 1%.
