Patent ID: 7409012

Claim:
A modulator comprising: a multi phase signal source including: a plurality of signal source outputs for outputting a plurality of phases of a carrier signal; a first phase selector including: a plurality of signal inputs coupled to the plurality of signal source outputs of the multi phase signal source; a first selector output for selectively outputting a first sequence of selected phases of the carrier signal; a second phase selector including: a plurality of signal inputs coupled to the plurality of signal source outputs of the multi phase signal source; a second selector output for selectively outputting a second sequence of selected phases of the carrier signal; a summer including: a first input coupled to the first selector output; a second input coupled to the second selector output; an output for outputting, in response to a signal received from the first selector and a signal concurrently received from the second selector, at least one weighted sum of the signal received from the first selector and the signal received from the second selector.
