Learn amplitude modulation with step-by-step circuit diagram, AM formula derivation, practical demonstration using BC547 transistor, and real oscilloscope results. Complete AM guide for electronics ...

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing.

This suggests that FM and PM can sound the same if the modulator signal is properly filtered, which is true. But most often these modulators are not filtered, and hence they can sound very different.

Learn how AM and FM modulation work, and how they impact radio waves and modern communication technologies.

New from Audemat at IBC2013 will be an updated version of the FM Modulation Analyzer. A new RF front end has been added to the unit and it is now available in two tailored and cost-effective packages.

Eh, maybe. PM and FM are closely related, but certainly distinguishable as modulation schemes in their own right. You can grab [nckm]’s code over on the gits, or check out the video demo below.

A method for broadcasting digital audio signals simultaneously with existing analog frequency modulation radio (88-108 MHz) in adjacent channels is presented. The digital transmission is based on ...

NovelSat, which performed a live test of its NS3 modulation technology at the 2012 NAB Show, said May 1, the technology demonstrated that HD channels can be broadcast with minimal space segment use ...
