PV_RectComb2 make gaps in spectrum

PV_RectComb2(bufferA,  bufferB,  numTeeth,  phase,  width)

Alternates blocks of bins between the two inputs.

bufferA - fft buffer A.

bufferB - fft buffer B.

numTeeth - number of teeth in the comb.

phase - starting phase of comb pulse.

width - pulse width of comb.
