These days when electronic circuits can be found almost anywhere, there is, some people fear*, a different kind of environmental pollution. They call it electrosmog (the word does not appear in any ...

A series of magnetic-field indicators detects attempts to affect measuring devices, such as utility meters, with magnetic fields coming from permanent magnets. The indicators can be used with water ...

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 ...
