Realization Of Frequency Measurement Based On Phase Processing

This topic in the traditional alignment method based on the pilot signal, provides adirect frequency measurement method, the frequency of processing for time phaseprocessing, the method of in-depth study will be conducive to a high frequency, ultrahigh frequency measurement. For RF to microwave and optical frequency frequencymeasurements provide a train of thought.In this high resolution frequency measurement principle based on the specificfrequency measurement scheme, according to the domestic and international currentsituation, find a phase processing method of frequency measurement, the use oflow-frequency signal sampling frequency of measured signal, capture the original signalsampling point, use them between the phase relationship of high frequency signalfrequency measurement.With the in-depth study, this technique is likely to become the forefront oftechnology measurement. To achieve higher frequency measurement to lay thefoundation...
