Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum ...
The frequency counter is built around a PIC16F84 microcontroller for the frequency range of 100Hz to 2.5GHz. The device utilizes an LCD with 16 characters in 2 lines and 12.8MHz TCXO with 1ppm. The ...
An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...
