An investigation of speech synthesis parameters
… synthesis. Six models were investigated: (1) series resonance; (2) direct form; (3) reflection coefficients; (4) area function; (5) parallel resonance; and (6) a simple articulatory model. Types (2,3,4) are three varieties of linear predictive coding (LPC) parameters. There are five parts to …

Low-Frequency Series Loaded Resonant Inverter Characterization
… operational characteristics of a low-frequency series loaded resonant inverter using a manually tunable inductor to achieve frequency stability and determine feasibility of utilization. Simulation and hardware results demonstrate elimination of switching losses via ZCS; however, significant …

Bragg reflector thin-film resonators for miniature PCS bandpass filters
… measured to be approximately -35ppm/°C for the series resonance and -15ppm/°C for the parallel resonance. The shift in frequency with temperature is attributed mainly to thermal expansion of the TFR constituent materials. The bandwidth was found to either increase or decrease with temperature, …

Generalized Frequency Plane Model of Integrated Electromagnetic Power Passives
… integrated modules, the high frequency parasitic resonance are normally significant and may have negative impact on the performance and EMI characteristics. However, the existing modeling technique can only predict the fundamental resonant frequency and showed neither the causes of the high …

Lithium niobate RF-MEMS oscillators for IoT, 5G and beyond
… RF-MEMS oscillators through harnessing over mode resonances for 5G and beyond. LiNbO3 resonators characterized by high-quality factor (Q), high electromechanical coupling (kt2), and high figure-of-merit (FoMRES= Q kt2) are crucial for building the envisioned high-performance oscillators. Those …

Analog Single Sideband-Pulse Width Modulation Processor for Parametric Acoustic Arrays
<p>Parametric acoustic arrays are ultrasonic-based loudspeakers that produce highly directive audio. The audio must first be preprocessed and modulated into an ultrasonic carrier before being emitted into the air, where it will self-demodulate in the far field. The resulting audio wave is …
