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。

If the modulation rate is high, it is possible to smooth out the pulse train using passive electronic filters and recover an average analog wave form.
如果调制率高,是有可能顺利进行,脉冲列车使用被动电子过滤器和收回平均模拟波形。

Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means.
