Although mainly oriented to digital modulations, Radiosim can also be used to solve
analog transmission problems. Here, the differential gain at 3.58 MHz due to a symmetrical
Butterworth filter is displayed. Four DC steps are applied to the FM modulator. The DG
variation is 3.5 % (differential gain and differential phase affect the transmission
quality of analog television).
The differential phase is not displayed here.
