一种新型不同频直接鉴相的锁相环
Novel phase-locked loop with direct phase detection for two frequency different signals
摘要
Abstract
It is difficult to do a frequency conversion using the current phase-locked technology when the input and output frequencies are approximatly equal or have an approximate integer multiple relationship.Based on the change law of the phase difference between the two different frequency signals,by using the phase coincidence detection circuits,the equivalent phase demodulation circuits and a filter with an adjustable bias,a new type of PLL is realized. Experimental studies are done with the results showing that the phase-locked loop has characteristics such as low noise,high stability,the easy-to-adjust output frequency.关键词
