A new modulation technique for AM broadcasting was demonstrated by industry pioneer Mike Dorrough at a recent meeting of SBE Chapter 43 in Sacramento. The Advanced Modulation System offers to increase ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...

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, ...

Belar Electronics has unveiled its latest innovations for analog and digital AM modulation, as the RF monitoring firm has completed its updates for its legacy AMMA-2. The company says this allows for ...

Who says AM radio is passé? Inovonics has sped up its market launch of its new 526 AM Modulation Monitor, and shipping has now commenced. Inovonics was expected to begin shipping the 526 in May. Gary ...

Frequency modulation (FM) is the method of conveying informations over a carrier wave by varying its frequency .This is different from the Amplitude Modulation (AM) in which the amplitude of the ...

(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 It was superseded by MFM and RLL.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 ...

It's time to fine tune the answer about a longstanding debate -- AM versus FM. Have you ever wondered why AM radio has so much more static than FM? To VERIFY, we reached out to our friends at 99.5 ...

XM has applied for a U.S. patent on a new method of FM modulation. Currently most cars do not include any kind of an auxiliary jack, so the method of choice for satellite radio is through FM ...
