数字频率计
说明: 设计一简易数字频率计,其基本要求是:
1)测量频率范围0~999999Hz;
2)最大读数999999HZ,闸门信号的采样时间为1s;.
3)被测信号可以是正弦波、三角波和方波;
4)显示方式为6位十进制数显示;
5)具有超过量程报警功能。
5)输入信号最大幅值可扩展。
6)测量误差小于+-0.1%。
7)完成全部设计后,可使用EWB进行仿真,检测试验设计电路的正确性。(The basic requirements of designing a simple digital frequency meter are:
1) The measuring frequency range is 0-999999 Hz.
2) The maximum reading is 999999HZ, and the sampling time of gate signal is 1 s.
3) The measured signal can be sine wave, triangle wave and square wave.
4) The display mode is 6-bit decimal number display.
5) It has alarm function beyond range.
5) The maximum amplitude of input signal can be expanded.
6) The measurement error is less than +0.1%.
7) After completing all the design, EWB can be used to simulate and test the correctness of the circuit.)
