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 project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 ...
