应用可变时间延迟实现频率迁移

Frequency Translation Using Variable Delay

本文分析了由电压控制时间延迟实现频率迁移的方案，利用电荷耦合器件（ＣＣＤ）或移位寄存器（ＳＲ）等器件可以实现这一方案。这一分析对应用多卜勒效应于测量、控制、雷达等实用技术有实际意义。

A voltege can be caused to experience a time delay that changes with time clocked storage elements sueh as Change-Coupled Devices(CCD)or Shift Registers(SR).An analysis shows this variable delay results in a translation of the frequency of the voltage.
