Modulation techniques for data superposition on amplitude-modulated signals [PDF]
, 1983 Double-sideband amplitude-modulation is widely used because of its simplicity in transmission and reception, but in a number of applications the inclusion of a data channel has become an additional requirement.

Tuning of human modulation filters is carrier-frequency dependent [PDF]
, 2013 Recent studies employing speech stimuli to investigate 'cocktail-party' listening have focused on entrainment of cortical activity to modulations at syllabic (5 Hz) and phonemic (20 Hz) rates.

High-Frequency Modulation Spectroscopy with a THz Quantum-Cascade Laser [PDF]
, 2013 A terahertz absorption spectrometer with a quantum-cascade laser (QCL) for high-resolution molecular spectroscopy is realized. The spectrometer is based on highfrequency (up to 50 MHz) modulation of the QCL frequency.

Modulation-frequency acts as a primary cue for auditory stream segregation [PDF]
, 2013 In our surrounding acoustic world sounds are produced by different sources and interfere with each other before arriving to the ears. A key function of the auditory system is to provide consistent and robust descriptions of the coherent sound groupings ...

BIFURCATION PHENOMENA IN VOLTAGE CONVERTER WITH FREQUENCY-PULSE CONTROL FOR A WIND GENERATOR
Известия Томского политехнического университета: Инжиниринг георесурсов, 2020 The relevance of the paper is determined by the need to improve energy efficiency parameters of power converting devices for the needs of alternative energy, in particular for a wind generator. One of the difficulties of converting wind energy is the low
