ABSTRACT:
A signal processing device for frequency multiplication of an analog signal by an adjustable multiplication factor. The input analog signal is digitized using a delta modulator and read into a random access memory at a first clock rate. The data is read out of the memory at second clock rate and then converted back to an analog output signal. The multiplication factor is a function of the adjustable ratio of the two clock rates.
