Abstract :
A frequency measurement system using a double-buffered method is designed for PC/AT compatible computers. The extremely wide range of measured frequencies (from 1.67 mHz to 7 MHz) is independent of a wide range of sampling periods (from 100 μs to 300 s). The response time to an instantaneously increased frequency from 1.67 mHz to 7 MHz is less than two sampling periods. The menu-driven software graphically presents frequency versus time to analyze fast frequency change using rapid sampling, or to measure the average frequency during long sampling periods
