Shortwave radio operates within the high-frequency (HF) band, typically between 3 to 30 MHz. Unlike AM and FM signals, shortwave signals can bounce off the ionosphere, allowing them to reach distances ...
Over radio’s first century of evolution as a broadcast medium, numerous innovations served to improve the efficiency of ...
Abstract: This letter introduces a below-resonant-frequency phase-shift modulation (BRFPSM) method to improve the light-load efficiency of CLLC converters. Traditional CLLC converters using pulse ...

Abstract: The interferometric fiber-optic gyroscope (IFOG) is an instrument for rotational motion monitoring. In IFOGs, frequency modulation is required for noise suppression. However, when the ...
Based on the observational and reanalysis data for 1979–2020, this study investigated the solar modulation of TC frequency over the western North Pacific in different solar cycle phases. Results ...
Similar modulation was also found in hearing-impaired mice, demonstrating that IC neurons receive non-auditory, locomotion-related neural signals. Sound-evoked activity was attenuated during ...
Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the ...
2008). It is hypothesized that lower-frequency oscillations coordinate information between areas by modulating excitability of local ensembles (von Stein and Sarnthein, 2000; Fries, 2005; Lisman and ...
