Patent abstract
Apparatus and methods for adjusting spectral characteristics of a polar modulation signal in a polar modulator are described. A detection circuit is configured to determine when an FM signal component of the modulation signal exceeds a threshold value. The output of the detection circuit is coupled with FM and AM mapping circuits to selectively map the FM signal component and an AM signal component of the modulation signal to mapped signals, thereby reducing FM deviation.
