Abstract: A frequency demodulator and method for demodulating frequency modulated (FM) signals, which may have been previously recorded on a recording medium, modulated in accordance with a video waveform, for example, wherein potentials are stored, for example, by capacitors, in response to selected half-periods of the recorded FM signals, and selecting, by auctioneering for example, one of the stored potentials which is indicative of the intelligence in the FM signals under consideration.

Abstract: A terminating impedance network is disclosed for communication signals transmitted by a power line carrier communication system to the premises of residential customers of an electric utility. Corrective impedance values suitable for communication signal terminations are established in the power line conductors serving the customer loads from a distribution network. Frequency sensitive low impedance values are established across the service conductors adjacent the customer loads to protect the communication system from interfering signals and high frequency noise originating in the customer loads.
