These boxes will not show nonlinearities in the modulation, they only
show if the range of modulation is not full. They do not show peak
limiting of excessive positive modulation or excessive negative
modulation. If they show any nonlinearities they are of the detector,
not the transmitter. But they will show pretty trapezoids because the
audio phase is always perfect.
