In other words, pulse width modulation is a modulation technique for generating variable width pulses to represent the amplitude of an input analog signal or wave.
或者换句话说，脉宽调制是一种调制技术，为发电可变脉冲宽度为代表的幅值输入模拟信号或波。

The relationships between GRI pulse sequences and reference pulses, as well as between modulation code groups and Loran-C pulse groups are analyzed.
分析了GRI脉冲序列与参考脉冲，以及调制码组与罗兰C脉冲组的时间关系。
