What Is a Digital Phase Shifter?
A digital phase shifter is a circuit that alters the phase of a digital signal.
The operating principle involves adjusting the phase based on the input digital signal and outputting a shifted signal. It finds diverse applications in communication, measurement, control, and more, featuring compact and lightweight characteristics.
It consists of flip-flops and circuits, where flip-flops store the value of the digital signal, and the circuit shifts the phase based on the output. There are various types such as delay line flip-flops and ring counters, contributing to changes in the waveform of digital signals.
Notable features include the ability to change the phase of digital signals and alter waveforms, coupled with excellent portability. Important considerations during use include compatibility with frequency and appropriate settings for phase shift amounts.
