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.

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.

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

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.

Frequency modulation has the advantage over both multiplicative (ring) and amplitude modulation in that the amplitudes of the individual sidebands vary as the modulation index is changed with each ...

Inovonics’ fourth generation “541” FM Modulation Monitor is now shipping to customers. What makes it noteworthy compared to previous versions of the product?

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 ...
