摘要
分析了数字式频率计,利用VHDL设计一种量程可自动转换的12位十进制等精度数字频率计,具有自动校验和测量功能,能用标准时钟校验测量精度,并具有超量程报警功能,超出当前测量量程档范围时能发出灯光和音响信号。
The digital cymometer is researched in the paper.Using VHDL,a automatic switching range, 12-bit decimal digital cymometer,with automatic calibration and measurement is designed,which can take advantage of the standard clock to calibrate measurement accuracy,and has over-range alarm function. When the measured signal beyond the current scope of when the measurement range.The digital cymonter can send lighting and sound signals.
