Abstract

In a receiver for synchronously demodulating real bandpass signals and including circuit elements connected for removing noise, equalizing the signals, converting the resulting signals to analytical signals, shifting the signals in phase, sampling the signals at the signal element timing rhythm, and interrogating the sampled signals, there is provided a single pair of filters serving to perform both the equalizing and converting functions.
