摘要
介绍“抗强噪声水层深度遥测装置”专利中,采用频分PPM(Pulse-Position modulation)方式进行多信息水声传输的研究和工程设计,并着重阐述产生PPM数字信号的新方法和应用特殊的数字选频滤波接收的先进技术,并提出所设计的有关电路。
The paper describes engineering design and development about using the frequency diversity PPM (pulse position modulation) mode to transmit multi-information in the patent 'A Water-layer-depth Telemeter with Resisting Strong Noise' , emphasizes a new method by which PPM digital signals are set up and an advanced technology by which digitized selective-frequency filter is adopted to receive the data, and presents the related circuits designed.
