介绍了一种以单片机为核心的智能型数字工频移相器 ,它采用环形队列实现工频信号波形的任意相位移相 ,且保持波形的幅度、频率不变。文中对其软、硬件的设计作了较为详细的阐述
An intelligent digital frequency-frequency phase shifter with a single-chip microcomputer as the core is introduced. It uses a circular queue to realize any phase shift of the power frequency signal waveform, and keeps the amplitude and frequency of the waveform unchanged. In this paper, the design of its software and hardware is described in more detail
