Using this experimental system, we have found that corticofugal modulation occurs in a specific and systematic way for the adjustment of auditory signal processing in the frequency and time domains.

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

Modulation index: Ratio of the frequency deviation to the frequency of the modulating wave in a frequency-modulation system when using a sinusoidal modulating wave. Fig. 1: Bessel function graph ...

Grey-cast, billiard-bald Major Edwin Howard Armstrong, deviser of the frequency modulation system of broadcasting, has twice in his time revolutionized radio—first by the regenerative, or ...

Frequency modulation technology has been used for surface mapping and measurement in sonar, radar, and time-of-flight laser technologies for decades.

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

Radio Frequency and Optical Fiber Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna.

Controlling this interference requires modulating the system's operating frequency. However, this modulation creates a mismatch between the modulated and resonant frequencies, severely degrading ...
