In this lab assignment, we will be concerned with the stedy-state response of electrical circuits to sinusoidal inputs 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 have three dfferent frequency, Wc, Wc/10, and 10Wc, and Wc is 2.2*10^5 Hz.
We also find the cutoff frequency for the circuit:
W: Wc Wc/10 10Wc
0.0321 /-45Ohm 0.0452/-5.711Ohm 4.52/-83.4 mOhm
A 22Ohm resistor and a 100uH inductor are used to set up circuit.
f=35KHz, Vin=989.4mV, and I=31.25mA. we got 0.0316/-37.8 ohm.
f=3.5k Ohm, Vin=973.4 mV, and I=38.55 mA. we got 0.0452/-6.3 Ohm.
f=350k Ohm, Vin=994.8 mV, and I= 5.665 mA. we got 5.695/-78.12 mOhm.
