Abstract
A system for measuring the capacitance of an electric signal conductor, with particular interest on telephone cables. A waveform generator produces a test signal which is coupled to the conductor. The resultant signal emerging from the conductor is delivered to a receiver, and then to an integrator, to produce an output signal which is a direct digital measure of the conductor's capacitance.
