Abstract
A fractional sequence generator having a plurality of cascaded accumulators whose carry-outs-upon-overflow are provided over a plurality of recombination paths and selective delays to an adder, the pattern of selective delays being modified by the addition of delay elements in all recombination paths except the last to reduce the number of quantization error terms in the transfer function of the sequence generator. Illustrative embodiments may have any number (greater than one) of accumulators and recombination paths, while continuing to exhibit desired simplified frequency response characteristics.
