The LF/MF model predicts basic transmission loss in the frequency range 0.01 - 30 MHz for propagation paths over a smooth Earth and antenna heights less than 50 meters. Additional bindings to the ...

Over half a million households will be forced to fit a smart meter or face higher bills within ... are energy-intensive and lack the quality of FM. Its advantage was that long-waves can travel ...

This involves several steps, such as selecting the frequency band and standard based on application requirements, choosing suitable components for the reader circuit, designing the layout and ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits ... the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of ...

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 ...
