(1) An earlier magnetic disk encoding method that places clock bits onto the medium along with the data bits. It was superseded by MFM and RLL. FM radio was invented in the early 1930s by Edwin Howard ...

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 ...

In quantum devices, frequency modulation is utilized in controlling interactions. A new article discusses the physics of frequency modulation in superconducting quantum circuits, ultracold atoms, ...

Xiaomi has been making all sorts of products and I came across the Roidmi 2s car charger that has the best quality FM modulator I’ve ever heard and a lot more features. Learn more in our full review.

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

Last month we looked at contributions to the art made by amateur operators, in particular advancements in Amplitude Modulation, or AM, and how it came to give radio its voice. This month, we will look ...

[Stephen] recently wrote in to share his experiments with using the LimeSDR mini to conduct a bit of piracy on the airwaves, and though we can’t immediately think of a legitimate application for ...

We are featuring the products that won the Radio World Best of Show Award at the recent NAB Show. Winners were chosen by a panel of radio engineers and RW editorial staff for their innovation, feature ...

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 ...

FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States in ...
