Abstract
Losslessly sampling a band-limited narrowband process at an average rate equal to the Nyquist rate may require a nonuniform sampling strategy. One such strategy ts phase quadrature sampling, in which a process of bandwidth B is sampled at rate Bin each of two channels where the two channels are n/2 out of phase at frequency B. Phase quadrature sampling is a special case of syncupated sampling, where the phase between channels is fixed but arbitrary, A simple method for recovering the spectrum of the input process from syncopated samples is derived. The derivation indicates what values of phase between channels result in lossless sampling.
