Claim One:
1. A modulation path synchronization apparatus in a polar transmitter, comprising: an amplitude modulation path to receive an amplitude training waveform and a phase modulation path to receive a frequency training waveform; a detector coupled to said modulation paths, said detector to detect modulated training waveforms; and a processor coupled to said detector, said processor to determine a delay between said training waveforms and said modulated training waveforms; wherein said detector is to detect a first modulated training waveform associated with said amplitude training waveform and to generate a first envelope waveform and said detector to detect a second modulated waveform associated with said frequency training waveform and generate a second envelope waveform; and wherein said processor is to correlate said first envelope waveform with said first amplitude training waveform to determine an amplitude modulation path delay; and said processor is to correlate said second envelope waveform with said frequency training waveform to determine a phase modulation path delay.
