Abstract
PURPOSE: To accomplish efficient transmission and reception at an excellent SN ratio by oscillating ultrasonic waves of resonant frequency during the transmission operation and by extracting the signals, which are prepared by modulating the received signals of resonant frequency into a fixed frequency other than the resonant level, during the receiving operation.
