Description of special functions 120
120: FM synthesis
This special function allows you to have the instrument synthesize the FM
signal in a digitized or linear manner. Digitized FM is best for signal-tone
modulation and provides very accurate center frequency at low deviation
rates. Linear FM is best for multi-tone modulation and provides a more
constant group delay than the Digitized FM.
