Abstract
A transmitting unit () clips a communication signal () to form a threshold-responsive signal (') which includes in-band distortion () and out-of-band distortion (). A portion of the out-of-band distortion () is notched within rejection bands () adjacent to the communication signal's bandwidth (). But remaining portions of the out-of-band distortion () and portions of the in-band distortion () are included with the communication signal (). The remaining portion of the out-of-band distortion () causes the communication signal () to be in violation of a spectral mask (). The mask-violating communication signalwith out-of-band distortion () and in-band distortion () is amplified by an RF power amplifier (). After amplification, a bandpass filter () exhibiting fast rolloff regions () attenuates the amplified out-of-band distortion () causing compliance with the spectral mask ().
