Harmonic Phasor Estimation Method Considering Dense Interharmonic Interference [PDF]
Entropy, 2023 Due to the limitation of frequency resolution and the spectrum leakage caused by signal windowing, the spectrums of harmonic and interharmonic components with close frequencies overlap each other. When the dense interharmonic (DI) components are close to

The Science of Harmony: A Psychophysical Basis for Perceptual Tensions and Resolutions in Music [PDF]
Research, 2019 This paper attempts to establish a psychophysical basis for both stationary (tension in chord sonorities) and transitional (resolution in chord progressions) harmony. Harmony studies the phenomenon of combining notes in music to produce a pleasing effect

Speed Variations in Cage Induction Motors Under Sinusoidal Voltage Modulation
Scientific Journal of Gdynia Maritime University, 2022 A specific case of voltage fluctuations is sinusoidal voltage modulation, which is a superposition of the fundamental voltage component and the subharmonic and interharmonic components – that is components of frequency less than the fundamental one or ...
