Probabilistic Amplitude Demodulation Features in Speech Synthesis for Improving Prosody

Amplitude demodulation (AM) is a signal decomposition technique by which a signal can be decomposed to a product of two signals, i.e, a quickly varying carrier and a slowly varying modulator. In this work, the probabilistic amplitude demodulation (PAD) fea ...

Remotely powered PPM demodulator by inductive coupling for rodent applications

Catherine Dehollain, Enver Gürhan Kilinç, Kerim Türe, Franco Maloberti

A low-power pulse position modulation (PPM) demodulator has been developed for remotely powered batteryless implantable devices. The required power for the implantable device is provided by the magnetic coupling with the external array of powering of coils ...

Demodulation of time series highlights impacts of hydrologic drivers on the Everglades ecosystem

Andrea Rinaldo

In the context of climatic uncertainty and potential climatic change, incorporating climatic variability and change in eco-hydrological analysis, as well as understanding the impact of such variability on ecosystems, is of crucial importance. The latter is ...

Correcting surface coil excitation inhomogeneities in single-shot SPEN MRI

Rolf Gruetter, Mor-Miri Mishkovsky, Jean-Noël Hyacinthe, Arnaud Comment, Nicolas Kunz

Given their high sensitivity and ability to limit the field of view (FOV), surface coils are often used in magnetic resonance spectroscopy (MRS) and imaging (MRI). A major downside of surface coils is their inherent radiofrequency (RF) B1 heterogeneity acr ...

Method for Increasing the Operating Distance of MEMS LIDAR beyond Brownian Noise Limitation

Niels Quack

A LIDAR based on a MEMS tunable VCSEL uses resonance tuning to increase the maximum range ten-fold. A novel demodulator reduces the peak electrical beat frequency from 52GHz to 235MHz for compatibility with standard CMOS. ...

Non-intrusive detection of rotating stall in pump-turbines

Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero

When operated far from their optimum conditions, pump-turbines may exhibit strong hydrodynamic instabilities, often called rotating stall, which lead to substantial increase of vibration and risk of mechanical failure. In the present study, we have investi ...

High Symbol Rate Coherent Optical Transmission Systems: 80 and 107 Gbaud

Rüdiger Urbanke, Luis Salamanca Miño

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...

Single-Cycle-PLL Detection for Real-Time FM-AFM Applications

Georg Fantner, Jens Anders, Blake William Erickson, Maja Dukic Pjanic

In this paper we present a novel architecture for phase-locked loop (PLL) based high-speed demodulation of fre- quency-modulated (FM) atomic force microscopy (AFM) signals. In our approach, we use single-sideband (SSB) frequency upcon- version to translate ...

Electronic Implants: Power Delivery and Management

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo, Seyedeh Sara Ghoreishizadeh

A power delivery system for implantable biosensors is presented. The system, embedded into a skin patch and located directly over the implantation area, is able to transfer up to 15 mW wirelessly through the body tissues by means of an inductive link. The ...

Sustained Nano-Mechanical Oscillation of a Resonant-Body Transistor by Frequency-Modulated Heterodyne Phase-Locked-Loop

Mihai Adrian Ionescu, Alexandru Rusu, Sebastian Thimotee Bartsch

Many applications based on resonant nanoelectromechanical systems (NEMS) require monitoring their natural frequency of oscillation over time with high precision, e.g. for gas sensing or nanomechanical mass spectrometry. In this study, we integrate a very-h ...
