For the particular lowpass filter you constructed in lab (f3dB ~
1 kHz) plot |H(f)| over the frequency range (0, 100 kHz) on a
semilogarithmic scale for the frequency, and use a linear scale in
dB for the vertical axis. To calculate|H(f)| simply solve for the
output voltage in terms of the input voltage—it should be a simple
voltage divider using the impedances of the capacitor and resistor.
