Homework Statement
I am trying to complete a lab about RC circuits. I was told to make a graph of both the high-pass and the low-pass filter (frequency vs. Vin/Vout). Then I was asked this question:
"Explain why the two lines on your graph should always cross at the frequency where XC =
R. Find this frequency from your component values and compare it to your graph. What
should Vout/Vin equal for each filter at that point?"
Homework Equations
I know of two equations that contain both Xc and R:
tan(phase) = -Xc / R
and
Z= sqrt(Xc^2 + R^2)
The Attempt at a Solution
I assume I am to use one of those equations to solve the problem, but I am confused as to where to start. Can you help?
