Autoranging Frequency Counter

EDA platform : Max+PlusII

design type : VHDL

 Description

  • This design is a useful measurement instrument to have around the lab to measure unknown frequency sources.
  • All of the required blocks are delf-contained "single-chip" design.
  • The maximum frequency counting range is limited by the technology of the device.

　

Documentation

  • The source code is extensively documented. So, please refer to them
