An approach to calculating interchannel distortion of linearly filtered angle-modulated signals using a hybrid computer

A time domain method suitable for hybrid simulation is developed to compute interchannel distortions due to linear transducers in FM systems. Multichannel baseband signals are simulated by sets of randomly phased sinusoids uniformly spaced in frequency. The distortion is computed by Monte Carlo trials. The method is fast and convenient for the user's interaction.
