ABSTRACT:
A direct digital-to-digital rate conversion apparatus and method for converting an input signal at a first sampling rate to an output signal at a second sampling rate, said apparatus has a rate multiplier means to increase the frequency of the input signal. The multiplied signals from the rate multiplied means are interpolated using a nth order n-polynomial interpolator to produce the output signal.
