Exponential frequency modulation bandwidth criterion for virtual analog applications
Optional Fields
Cross modulation or Exponential FM is a sound synthesis technique associated with modular analog subtractive synthesizers. It differs from the more well-known linear FM synthesis technique in that the modulation is an exponential function of the control voltage. Its spectrum shape is more complex, thus giving it a larger bandwidth with respect to the modulation depth. Thus, the prevention of aliasing distortion requires different conditions than Carson's rule as used with linear FM. A suitable equation will be presented in this paper.
