Abstract
Digital signal receivers for detecting BPSK modulation of a suppressed carrier transmitted through the same channel as an analog television signal are described, in which the detected BPSK is digitized with an oversampling analog-to-digital converter prior to digital comb filtering for separating the BPSK from interfering analog television signal remnants. This is done to get an increased number of bits resolution from a relatively inexpensive flash converter so that the BPSK, which is of relatively low amplitude compared to maximally interfering analog television signal remnants, is not overwhelmed by quantizing noise. The oversampling analog-to-digital converter can be of sigma-delta type.
