A limit of the Phase-shifter is its phase shifting range. The output functions at
the
Phi -output jacks: ,namely saw-tooth, triangle, sine, and 50% rectangle with
half frequency can be shifted referred to the VCO core (Omega-outputs) by
maximum 360° (±2
π
, radian measure) with the
Phi -controller: The phasing of the waves by itself has no effect of their sound
and spectrum. Only changes of the phase causes real frequency shifts at the
Phase-shifters' output.
This fact is one of the big differences to the FM. And this, finally , means that
the modulation index goes proportional to the modulation frequency without
any physically limit! So, the index is
not a constant as for the FM. Fig. 7b shows
the PM result for the as twice higher modulation frequency without doubling
the index as it would be necessary for the FM to get the same result.
