Abstract
A BPSK type reception device that includes a decoder for decoding a digital input signal, first and second comparators for delivering a decoded data signal and a data capture clock signal also includes a clock generator for generating a replacement clock signal, first and second latches controlled by the replacement clock signal to store the data taken, respectively, from the decoded data signal and from a signal that represents the sign of the signal at the output of the decoder, and a selection circuit for capturing, at each pulse edge of a clock signal that is offset with respect to the replacement clock signal, either the stored data originating in the sign signal in the case of loss of the previous data capture clock pulse edge at the output of the clock comparator, or the stored data originating in the data signal.
