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 ...

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 ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

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 ...

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 ...

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 ...

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 ...

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, ...

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, ...
