2、rilogHDL语言设计了一个简单的数字频率计的过程关键词：周期；EDA；VerilogHDL；数字频率计；波形仿真SummaryInelectronics, the frequencyis one of the most basic parameters, and measurementprogram with a lotofelectricparameters,themeasurementresult-s haveaverycloserelationship, and frequency measurement becomes moreimportant.
3、Thereareseveralways of measuringfrequency, the electronic countertomeasure frequency with highprecision, easytouse, rapid measurement,and easy to automate themeasurementprocess,etc., is one of the important means of frequencymeasurement. Electroniccounter frequencymeasurement intwowa
4、ys: First,thedirect frequencymeasurementmethod to measure the number of pulses of the measured signal,thatis, in acertain gatetime; indirect frequencymeasurementmethod, suchas the cycle frequencymeasurementmethod. Direct frequencymeasurementmethod for high-frequency signal frequencym
