This frequency counter is [Miguel Pedroso’s] entry in the 7400 Logic contest. After looking at the design we think this is a perfect project for those who have not worked with logic ICs before. The ...

Have you ever started a project, run into an issue, started a new project to solve the issue, and completely forgot about the original project? [Andy] went down a rabbit hole of needing a tool to ...

The PIC16C5X has one 8-bit timer (Timer0), which can be used with an 8-bit prescaler. The prescaler runs asynchronously, hence it can count a very high frequency. The minimum rise and fall times of ...

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 frequency counters, the gating time allotted for counting is often too short to resolve low frequencies. A phase-locked loop could be used to multiply the input frequency. But in some cases, the ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

B&K Precision has introduced a pair of 10 digit frequency counters reaching 3 or 6GHz, with ±1ppm stability across their +5 to +40°C operating range. “This series utilizes a reciprocal counting ...

Hermetic Word Frequency Counter Advanced may flash you back to the days of Pets.com and the blink tag, but there’s a lot of utility here. Hermetic Word Frequency Counter Advanced is a useful utility ...

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 ...
