We demonstrated the concept and implementation of this graphene-based sensing modulator through a frequency-modulation (FM) experiment conducted in a modulation cycle consisting of alternating ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of ...

This tutorial explains the fundamentals of time-, frequency-, and modulation-domain analysis from the perspective of several examples.

Molly J. Henry, Jonas Obleser, Frequency modulation entrains slow neural oscillations and optimizes human listening behavior, Proceedings of the National Academy of Sciences of the United States of ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

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

NTT Corporation and Tokyo Denki University have succeeded in further stabilizing the graduated frequency of an optical frequency ruler generated by modulating the intensity and phase of laser ...
