ABSTRACT:
A randomization unit for use in a vibrational control system for generating a series of randomized drive terms where the magnitude of each randomized drive term is the convolution of a psuedo-random sequence of bistable signals and a drive data sequence characterized by a drive power spectral density (PSD). The randomization unit does not required multipliers to perform the convolution operation.
