The circuit is a simple digital frequency meter that is made of a frequency-to-voltage converter and an analog-to-digital display converter that can be operatedfrom a single 9-volt battery. The TC7126 ...

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 ...

The circuit was designed to measure the electric field strength in radio frequency band where it can be applied during the modulation of AM and FM signals in the VHF range. Field Strength – the ...

Widespread deployment of electric utility smart meters in the United States and other countries has prompted a need to characterize the electromagnetic environment produced by these devices. In an ...
