本文介绍了基于FPGA的数字频率计的设计方法，设计采用硬件描述语言Verilog ，在软件开发平台ISE上完成，可以在较高速时钟频率（48MHz）下正常工作。该数字频率计采用测频的方法，能准确的测量频率在10Hz到100MHz之间的信号。-This article describes the FPGA-based digital frequency meter design method using hardware descr iption language Verilog, ISE on the complete software development platform, can be compared with high-speed clock frequency (48MHz) to work properly. The digital frequency meter using frequency measurement method, can accurately measure the frequency of the signal between 10Hz to 100MHz.
