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 ...

Many passive field strength meters have appeared in the past, typically using a 50mA analog meter movement if reasonable sensitivity was to be obtained. This circuit is similar but has the advantage ...

Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals ...

The original Ghostbusters movie is a classic that’s still delivering nearly 40 years after its release — just let that sink in for a minute. Almost every aspect of the film, from hand props to quotes, ...
