1. An ultrasonic system, comprising:
- an ultrasonic transmitter for emitting a transmission signal, the emitted transmission signal including a synchronous burst and a plurality of data bursts, wherein the synchronous burst serves to activate a communication mode, and the data bursts represent data information being transmitted; and
an ultrasonic receiver for receiving a synchronous echo and determining whether the amplitude of the synchronous echo is larger than a first threshold,wherein if the amplitude of the synchronous echo is larger than the first threshold, then the ultrasonic receiver interprets a plurality of data echoes corresponding to the data bursts back to the data information.

Abstract
An ultrasonic system including an ultrasonic transmitter and an ultrasonic receiver is provided. The ultrasonic transmitter emits a transmission signal, which includes a synchronous burst and multiple data bursts. The ultrasonic receiver receives a synchronous echo, and determines whether the amplitude of the synchronous echo is larger than a first threshold. If the amplitude of the synchronous echo is larger than the first threshold, then the ultrasonic receiver interprets the multiple data echoes corresponding to the data bursts to obtain a digital signal.
