The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great ...

The project utilizes an AVR controller that can be used as a counter by being more involved with a PIC which has synchronous counter input. The PIC input can handle frequencies up to 40MHz.

The project was created to turn a multimeter into a sensitive frequency counter with a wide counting range. An old frequency counter can be upgraded using this project and the range can be extended up ...

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 ...

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has developed a broadband and high-precision terahertz (THz) frequency counter based on a ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...
