Robust Resonance due to Non-standard Frequency Modulation
Oleg V. Gendelman, Luis M. Baldelomar Pinto, Lawrence A. Bergman +1
It is shown that harmonic signals incorporating a new type of weak non-standard frequency modulation (wNSFM) have unexpected spectral properties, namely, ever expanding broadband f…

Time-bandwidth Study of Non-classically Damped, Linear, Time-invariant Coupled Oscillators with Closely Spaced Modes
Luis M. Baldelomar Pinto, Alireza Mojahed, Sobhan Mohammadi +3
In dynamics and vibrations, the concept of bandwidth for linear time-invariant systems is widely recognized as a measure of the dispersion of frequency content around resonance. Si…
