The device is a simple, small, and cheap frequency meter with out any hard to find components to be able to measure frequencies up to 40 MHz while having below 1% errors. Most of the analog and ...

This sound frequency meter circuit is simple to build and can be constructed in a portable format. In can measure frequencies with a minimum level of 10 mVrms and a maximum frequency of up to 100kHz.

This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...

Not only since the total power outage on the Iberian Peninsula last spring has the quality of electrical power supply come ...

Anritsu has created a frequency-selective portable power meter that will operate from 9kHz to 70GHz. Called Power Master MA24507A, the mm wave tester is designed to work with a host computer running ...

Everybody already knows what bandwidth is and how it is measured. The problem is the definition: bandwidth is defined and measured in remarkably different ways by different people. In the basic scheme ...
