【正文】 , sine wave, square wave function waveform generator. This topic used jointly by the integrated operational amplifier with transistor differential amplifier consisting of square wave triangular wave sine function generator design method, the first parator generates a square wave, triangular wave generated through the integrator, formed by the differential amplifier sine . Waveform conversion principle is to use nonlinear differential amplifier transfer characteristic curve.Digital frequency meter is a timing circuit, it is mainly constituted by the flipflop has a memory function. , Have been widely used in puter and digital instrument. In electronic technology, the frequency is one of the most basic parameters, and many electrical parameter measurement solutions, the measurement results are very close relationship between the frequency measurement bees more important. Measurement frequency variety, electronic counter measures the frequency with high precision, easy to use, rapid measurement, as well as facilitate the realization of the measurement process automation is one of the important means of frequency measurementKey words: Function signal generator, square wave, triangle wave, sine waveDigital frequency meter, measurement frequency, process automation, triggers目錄1. 前言12. 總體方案設計23. 設計原理34. 電路調(diào)試與仿真115. 心得體會156. 參考文獻177. 附錄18261 前言頻率是周期信號每秒鐘內(nèi)所含的周期數(shù)值。而后面的閘門或計數(shù)電路要求被測信號為矩形波，所以需要設計一個整形電路則在測量的時候，首先通過整形電路將正弦波或者三角波轉(zhuǎn)化成矩形波。所以在通過整形之前通過放大衰減處理。當輸入信號電壓幅度較小時，前
