Abstract
A fractional sequence generator for use in a F-N synthesizer includes a multi-accumulator structure providing a plurality of carry-out signals for application to an adder through a recombination network to generate an output fractional sequence, S, having an average value given by avg(S)=C/D, where C/D is the desired fractional part of the divisor, and denominator, D, is programmable. Illustratively, contents of a n-bit accumulator in each accumulator is augmented by a function of the programmable denominator value upon a carry-out of the associated n-bit adder in that accumulator.
