; 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.
