Abstract

The demodulation system converts the received signals into an intermediate frequency using a formula expressed in terms of the clock frequency of the modulated information, with signal sampling using a sampling period which corresponds to the reciprocal of the clock frequency. Pref. the intermediate frequency is obtd. from a quarter wavelength of the clock frequency summated with an odd or even multiple of half the clock frequency.
