Abstract
A method and apparatus for defining and generating a digital waveform such as used for the local oscillator for a down converter in a receiver is disclosed. The method and apparatus is particularly useful where the digital waveform is not an integer submultiple of a reference signal. A plurality of different digital waveforms meeting the timing criteria but having different combinations of segments needed to meet the timing criteria are generated. Each of the digital waveforms so generated are tested in, for instance, a receiver to enable the selection of the best combination of segments.
