摘要
An ultrasonic communication circuit is disclosed. The circuit includes an ultrasonic transmitter arranged to transmit a training signal having a frequency to a remote transceiver over an ultrasonic communication channel. An ultrasonic receiver is arranged to receive information from the remote transceiver in response to the training signal. The ultrasonic transmitter is arranged to transmit a data signal to the remote transceiver. The data signal has a duty cycle determined by the information.
