摘要

本文证明了在±0.637V范围内的任何限带信号都可以用幅度为v的PWM波形表示，该波形中脉冲的个数等于奈奎斯特采样的个数。本文还提供了一个实用的迭代过程来生成给定带限信号的PWM波形。该过程的误差随迭代次数呈指数递减。

Exact PWM representation of bandlimited signals

This paper proves that any bandlimited signal within ±0.637V can be represented by a PWM waveform with amplitude V. The number of the pulses in the waveform is equal to the number of the Nyquist samples. This paper also provides a practical iterative procedure to generate the PWM waveform for a given bandlimited signal. The error of this procedure decreases exponentially with the number of iterations.
