In practice we might not know the waveform ahead of time and we would be asked to examine the phasor amplitudes and phases and use Fig. 2-2 to determine ... a third out-of-band frequency to see the degradation of the in-band two-tone signal. This can be very illuminating and very practical. Example 2-1: Nonlinear AmpliÞer Distortion and Squ...
