Heart auscultation is a widely used technique for diagnosing cardiac abnormalities. In that
context, capturing of phonocardiogram (PCG) signals and automatically monitoring of the …

Epoch location is an important parameter for analysis of excitation source information from
the speech signals. From several years lot of research have been done to find accurate …

Zero frequency filtering (ZFF) is a well-explored technique for detecting glottal closure
instants (GCIs) from the speech signal. The features extracted from the ZFF of the speech …

Epoch extraction has become increasingly popular in recent years for speech analysis
research because accurately detecting the location of the Epoch is crucial for analyzing …

Voice activity detection (VAD), is a signal processing technique used to determine whether a
given speech signal contains voiced or unvoiced segments. VAD is used in various …

A 5 th-order tunable IIR digital low-pass filter is presented which can operate from 20 to 70
MHz at a 176-MHz sampling frequency. The number of input and output bits is 14 and 15 …

Epoch is the instant at which significant excitation of vocal tract filter takes place during the
production of speech phonation. The extraction of epochs helps in speech enhancement …

This study presents an optimized noise reduction hardware architecture for a real
electrooculogram (EOG) system. The proposed denoising architecture uses a differential …
