We propose a new channel compensation method for modulation spectral features. We compare our proposed method, subband normalization, with a more traditional method, cepstral mean...
The piecewise-linear approximation technique developed by Juli´an et al. in the past few years is applied to dynamical systems dependent on given numbers of state variables and p...
A compact integrated CMOS circuit for temporal differentiation is presented. It consists of a high-gain inverting amplifier, an active non-linear transconductance and a capacitor...
A mixed-signal architecture for estimating the 3-D direction cosines of a broadband traveling wave impinging on an array of four sensors is presented. The architecture implements ...
The goal of the research is twofold First, the derivation of a design methodology for FIR filters implementation based on Residue Number System (RNS), aiming at power, delay and h...

The most popular speech feature extractor used in automatic speech recognition (ASR) systems today is the mel frequency cepstral coefficient (mfcc) algorithm. Introduced in 1980,...
Couple to the communications wired and unwired networks growth, is the increasing demand for strong secure data transmission. New cryptographic standards are developed, and new en...
This paper will present a practical and complete analysis of timing-mismatch effects for high-speed Analog Front-End (AFE) systems with the inherent nonuniformly holding outputs. ...
