Frequency Modulation (FM) Dialog

For convenience, the FM dialog includes duplicates of the main carrier phase and frequency controls that are also in the Tone Freq dialog, plus controls to select the modulator source and modulation deviation (depth), as well as to set the frequency and phase of the dedicated sine source if that is selected.

Unlike AM and Burst, FM is not an available option for noise-type waves, or for Arb or Play waves where the Step Timing option has been selected. However, note that it is possible to modulate the frequency of a noise band by a special use of amplitude modulation.
