Abstract
Detecting vibration of a cable including providing a clock signal along a cable, the clock signal is modulated along the cable by a vibration frequency to generate a modulated signal along the cable that includes upper and lower sideband frequencies with respect a frequency of the clock signal; providing the modulated signal to a multiplexer, a positive polarity signal of the modulated signal is provided to a first input line of the multiplexer and a negative polarity signal of the modulated signal is provided to a second input line of the multiplexer; selecting one of the positive polarity signal and the negative polarity signal based on a state of a reference signal; demodulating, based on the selecting, the modulated signal to generate a demodulated signal, including generating the vibration frequency at a baseband of the demodulated signal; filtering the demodulated signal to obtain filtered signal including only the vibration frequency.
