- ; Example6.dat - 50 ohm, 5th order, 5MHz Butterworth low-pass filter
- ; This example will show how to calculate input impedance.
- ; Set the number of sample points to 140 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.
