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 ...

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.

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.

Abstract An improved F.M. modulator and demodulator are described which are suitable for the transmission of television signals through a field-store standards converter. They represent an ...

A proposed Extensible SOQPSK modulation waveform brings the best of both OFDM modulation and single-carrier SOQPSK modulation to telemetry applications.

“IDE approval from the FDA represents a significant milestone for Presidio and enables the study of ultra low frequency modulation of the nervous system.

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.
