A receiving circuit has a speech/no-speech signal detector for detecting whether there is a speech signal or not based on data inversely diffused by finger receivers, and a clock controller for controlling operation of the finger receivers based on a detected result from the speech/no-speech signal

A receiving circuit has a speech/no-speech signal detector for detecting whether there is a speech signal or not based on data inversely diffused by finger receivers, and a clock controller for controlling operation of the finger receivers based on a detected result from the speech/no-speech signal detector. If a speech signal is detected by the speech/no-speech signal detector, then the clock controller controls all the finger receivers to operate. If no speech signal is detected by the speech/no-speech signal detector, then the clock controller controls only one or two of the finger receivers to operate.
