Harmonic vector excitation coding of speech
Acoustical Science and Technology, 2006A coding algorithm for speech called harmonic vector excitation coding (HVXC) has been developed that encodes speech at very low bit rates (2.0–4.0 kbit/s). It breaks speech signals down into two types of segments: voiced segments, for which a parametric representation of harmonic spectral magnitudes of LPC residual signals is used; and unvoiced ...

Performance of Non-linear Vibration Isolators Under Harmonic Excitation
Journal of Sound and Vibration, 1994Vibration isolators having non-linearity in both stiffness and damping terms are analyzed under harmonic excitations. Isolators with symmetric as well as asymmetric restoring forces are considered. The method of harmonic balance is used to obtain the steady state, harmonic response and transmissibility under both force and base excitations.

Non-linear vibrations of a harmonically excited autoparametric system
Journal of Sound and Vibration, 1982Harmonic forced vibration of a spring-mass-damper system with a parametrically excited pendulum hinged to the mass is investigated. Two types of restoring forces on the pendulum are considered. The method of harmonic balance is used to evaluate the system response. The results are also verified by numerical integration.

Experimental study of gear rattle excited by a multi-harmonic excitation
Applied Acoustics, 2007Abstract This paper deals with the rattle noise, caused by the fluctuations of the engine torque (acyclic excitation) which, under special conditions, can cause multiple impacts inside the gearbox. Its aim is to experimentally describe the rattle phenomenon in a gearbox.
