Homework Statement
Make a blode plot of a series RC high pass filter (log(gain) vs. f)...
Homework Equations
log(Gain)=log(Vout/Vin)
I'm pretty sure the "Gain" is just the transfer function, for a highpass it should be the V_in = Vsupply, and V_out = V_capacitor.
The Attempt at a Solution
I have an RC circuit hooked up and I'm going to make the bode plot taking data from the oscilloscope, I'm just going to vary the frequency and collect voltages, but I'm not sure how to go about doing it because of the phase difference between the input voltages (Ch. 2 blue line) and the output voltage (over the capacitor, Ch.1 yellow line).
Can I just measure peak-to-peak? I'm not 100% sure if that's correct because of the phase difference between peaks. Do I need to take voltages over the same point on the "time" axis or is peak-to-peak ok even if at different points with respect to time axis?
