一种脉冲间隔编码的实现方法

摘要

脉冲编码主要有重频编码、周期编码、脉冲间隔编码(PCM编码)及伪随机码4种码型样式，各种脉冲编码中脉冲间隔编码的应用最为广泛。文中以基础频率为5~50 Hz、1~12 bits可变码位的脉冲间隔编码为研究对象，对脉冲间隔编码的特点及生成机理进行分析，并通过实际的硬件、软件设计讨论其实现方法，最终给出几种脉冲间隔编码的输出结果。%Pulse code mainly includes four kinds of codes such as repetition frequency code, cycle code, pulse code modulation (PCM) code and pseudo-random code, and among which PCM code is the most widely used. PCM code with variable code bit and basic frequency of 1~12 bits and 5~50 Hz is researched. Characteris⁃tics and generation principles of PCM code are analyzed. Based on the design of actual hardware and software, implement methods are discussed. Output results of different PCM codes are given finally.
