Abstract
A method for estimating cable length includes steps of generating a detection signal to a cable, wherein the detection signal includes a first pulse and a second pulse with opposite voltages in sequence; receiving a refection signal of the detection signal from the cable; and determining length of the cable according to a superposed waveform of the detection signal and the refection signal.
