Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Abstract: Frequency modulation is widely utilized in inductive power transfer systems and is also included in the Qi standard for low-power chargers. This brief examines small-signal modeling and ...

Abstract: In this paper a study of the effect of integral pulse frequency modulation (IPFM) on single-input single-output feedback control is attempted. For zero input such systems can be reduced to a ...

The auditory system has the potential for reorganization as a function of experience. In particular, corticofugal projections can affect the properties of subcortical neurons in response to sound.

/ c ± n.m / for n = 0, 1, 2, 3, .... where n is the sideband pair number In this expression, the + indicates the upper sidebands, and the - indicates lower ones ...

To increase the reserve capacity of the frequency modulation system, the load capacity of the wind turbines is reduced. In (Wu et al., 2013; Tan et al., 2016), To solve the problem of insufficient ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

In the Dec. 7 issue of RWEE, we asked: What is a Bessel function and what is a typical application? a. A numerical description of propagation through a solid body, most often used in coax design. b. A ...

Recently, the team of Xue Xiaoxiao and Zheng Xiaoping from the Department of Electronic Engineering at Tsinghua University ...

Proposals have been made for field-stone television standards converters using ultrasonic delays as storage devices. Previous experiments have shown that variations of gain of the amplifiers ...
