Figure Legend:
Effect of half-wave rectification and partition into ON- and OFF-channels on the DC component and the first four harmonics of waveforms from a half-wave rectifier in response to an input waveform that consists only of the first and second harmonics. Amplitude at the output of the half-wave rectifiers is shown as a function of the phase of the second harmonic at the input to the half-wave rectifiers. At the input, the second harmonic had half the amplitude of the fundamental. Solid lines show the amplitudes in the ON pathway, dashed lines, the amplitude in the OFF pathway. The DC component (black line), the third (blue line), and fourth (purple line) harmonics are identical in the ON and OFF pathways but the first (red lines) and second (green lines) differ markedly in the two pathways.
