ABSTRACT:
A fault detection system is provided for detecting and locating faulty connections in a cable TV system. First and second signals are generated at the head end transmitter. The first signal is a continuous wave signal. The second signal is a pulse modulated sine wave signal. A fault is indicated by the reception of a beat frequency signal between the first and second signals generated at the location of the faulty connection and returned to the head end. The location of the fault is determined by measuring the time interval between the transmission of the first and second signal and the return of the beat frequency signal, and relating such time interval measurement to the corresponding distance between the head end and the faulty connection.
