[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

The circuit was designed to operate a frequency modulation voice transmitter over the FM band 2 frequency range of VHF. Transmitter – an electronic device that can produce or amplify a carrier wave ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...

This article was originally published in the Jan. 20, 2016 issue of Radio World Engineering Extra. “Milestones” is a series of reminiscences about notable radio technological developments. Some of us ...

You're going on a road trip. This isn't a question - it's summer and I know you're gearing up to take the family on that Griswold vacation that will leave you craving anything but fast food and ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

THE communication of intelligence by means of radio frequency electric waves is effected either by interrupting the waves into groups of long and short duration, or by varying the amplitude, frequency ...
