數(shù)字頻率計是電工電子中常用的測量儀器,數(shù)字頻率計通過用輸入待測信號對一特定長度的信號進(jìn)行計數(shù),從而得出頻率并通過數(shù)碼管直觀的顯示出來。本文提出了一種與輸入同步的數(shù)字頻率計的設(shè)計,提高了頻率計的精度,設(shè)計采用Multisim軟件進(jìn)行設(shè)計和仿真的過程,介紹了其工作原理,硬件電路設(shè)計和仿真的過程。設(shè)計采用了Multisim軟件進(jìn)行設(shè)計和仿真,設(shè)計結(jié)果得到的驗證。Digital frequency counter is used to measure the frequency of a signal.It is common to use a multivibrator to generate a standard 1 second time base signal and count input signal gated by this signal.However,the ASYNCHRONOUS of this time base signal with input signal will bring errors.In this paper,a high precision frequency counter which use synchronized time base signal generator is proposed.This frequency counter is designed and simulated by Multisim tools and result is verified.
