pulse time code

基本解释

This technique uses different time delay values of the LFM pulse to code the transmitted information, and uses time delay estimation technique to perform decoding.
该技术利用线性调频信号（LFM）矩形脉冲的时延值进行时延编码，在接收端采用时延估计技术进行时延解码。
In this paper, the PPM-PTC(Pulse Potential Modulation-Pulse Time Code) are designed to transmit the acoustic information of the cathodic protection potential of the subsea pipeline.
本文设计了PPM-PTC（脉位调制-脉冲周期编码）信息水声编码方式并将其运用于海底管线保护电位水声遥测系统中；

Shannon would also contribute to the further development of pulse-code modulation (along with Bell alumni Bernard M Oliver and John R Pierce) at around the same time, using technology that eliminated some of the issues (such as complex circuitry) from the earlier, but conceptually similar, implementation from Briton Alec Reeves in 1938.
