LFMCW雷达目标检测问题最终可归结为对差频信号的处理。
The problem of LFMCW radar target detection, in essential, is the beat signal processing.
作为另一个示例，选择信号的逻辑状态可响应于提供给脉冲频率检测器的电源电压的变化而改变。
As another example, the logic state of the select signal can be changed in response to a change in the power supply voltage provided to the phase frequency detector.
