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 ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

Here’s a question: when did you last listen to an AM radio station? If your answer is “recently”, chances are you are in the minority. You might ask: why should you listen to AM? And you’d have a ...

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 ...

Gary Peterson makes great points about the history of AM modulation (Reader’s Forum, “Modulation Limits,” Sept. 16 issue). I’d like to add to that by including a note about one of the most unique ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

West Chester, PA, October 23, 2017 — Belar Electronics has unveiled its latest innovations for analog and digital AM modulation, as the RF monitoring pioneer updates its legacy AMMA-2 system for more ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

We’ve been loving the variety of entries to the 2025 One-Hertz Challenge. Many a clock has been entered, to be sure, but also some projects that step well outside simple timekeeping. Case in point, ...
