本文提出了定时脉冲间隔调制(TPIM)方式,它属于非严格同步的脉冲模拟调制方式。该方式克服了脉冲间隔调制(PIM)存在的几个难点,实现起来更加方便、经济、可靠,通信质量亦能达到规定指标,与现有的其它调制方式相比,有许多独特的优点。论文的主要工作分理论和实验两大部分。完成的理论工作包括: 1. 分析了TPIM调制和解调输出波形的频谱。TPIM调制输出波形是位置随信号变化
This paper presents a timing pulse interval modulation (TPIM) method, which belongs to the non-strictly synchronized pulse analog modulation. This method overcomes several difficulties of pulse interval modulation (PIM), and is more convenient, economical and reliable, and the communication quality can reach the specified index. Compared with other existing modulation modes, there are many unique advantages. The main work of the thesis sub-theory and experiment two parts. The completed theoretical work includes: 1. Analyzing the spectrum of the TPIM modulation and demodulation output waveform. The TPIM modulation output waveform is position dependent on the signal
