Abstract
A variable rate modulator for selectively encoding a variable rate data stream according to one of a plurality of modulation formats. A timing and control circuit locks the variable rate data to a master clock, an encoder selectively encodes the data according to one of a plurality of modulation formats, and a polyphase filter performs pulse shaping and interpolation functions using only shift and add functions to produce a DAC-ready output signal.
