; Example7.dat - 50 ohm, 5th order, 5MHz Butterworth low-pass filter ; This example will show how to calculate return loss. ; Set the number of sample points to 280 for this circuit. ; RS is the impedance of the source, normally this is 50 ohms, ; but it must be set to 0 if you want to calculate impedance, VSWR, ; or return loss.
