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 ...

Frequency! It’s an important thing to measure, which is why [Jacques Pelletier] built a frequency counter some time ago. The four-function unit is humble, capable, and also an entry into our 2025 One ...

7 or more digits frequency counters are precision instruments used to measure the frequency of an electrical signal. They display the frequency in Hertz (Hz) with a high degree of accuracy, often up ...

Image Credit: Allied Electronics, Inc. Frequency counters are digital devices for accurate measurement and display of square wave and pulse input signal frequencies. A frequency counter is an ...

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 ...

Everyone loves a bargain. Who doesn’t love a hacked oscilloscope? Well, it would be unusual for an oscilloscope company to teach you how to hack your own hardware. Besides, that’s already been done ...

Tektronix has introduced two counter/analyser ranges, including a 20GHz timer/counter and a microwave counter which operates up to 40GHz. The instruments provide 250,000 samples/s data transfer rate ...

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 ...
