The exception is an isolated burst of several cycles of a sinewave.
For non-sinusoidal waveforms a sine interpolator is usually
inappropriate, except in the case of certain instruments which can
suitably pre-process the waveform before passing it to the sine
interpolator. The effect of a sine interpolator on a step waveform
