Effects of low-pass filtering on the judgment of vocal affect in speech directed to infants, adults and foreigners. ACCEPTED MANUSCRIPT 2 ABSTRACT Low-pass filtering has been used in emotional research to remove the semantic content from speech on the assumption that the relevant acoustic cues for vocal affect

This paper presents design, simulation, fabrication and electrical analysis of a triple notched band UWB band pass filter. Short circuit stubs and microstrip line defected structures are used to design a triple notched band UWB filter. The proposed UWB BPF consists of five short circuited stubs of quarter wavelength attached to the feed line. The notched bands are created by introducing three U...

Wavelet decomposition of signals using the classical Daubechies-Wavelets could also be considered as a decomposition using a filter bank with two channels, a low pass and a high pass channel, represented by the father and mother wavelet, respectively. By generalizing this two channel approach filter banks with N ≥ 2 channels can be constructed. They possess one scaling function or father wavele...

This project is intended to build a microstrip low pass filter with a pass band till 3 GHz at 3 dB cutoff frequency. This project is divided into two stages. In the first stage, a conventional seven pole low pass filter using commensurate length 8 / g λ is designed by converting the value of g1 to g7 into unit elements as well as open circuit stubs. In second stage, a method to design low pass ...

BACKGROUND Dominant frequency (DF) analysis of atrial electrograms has become an important method in characterizing atrial fibrillation (AF). As a classic method, Botteron's approach is widely used in the preprocessing of frequency analysis during AF. It includes three steps: (1) band-pass filtering at 40-250 Hz, (2) absolute value, and (3) low-pass filtering at 20 Hz. This paper aims to expoun...

In this paper, a simple but effective method for compensation of the quadrature error in MEMS vibratory gyroscope is provided. The proposed method does not require any change in the sensor structure, or additional circuit in the feedback path. The mathematical relations of the proposed feedback readout system were analyzed and the proposed solution assures good rejection capabilities. Based on ...

Pairs of Thai tones were presented for perceptual discrimination in three linguistic contexts (normal speech, low-pass filtered speech, and as musical (violin) sounds) to tonal language speakers, Thai and Cantonese, and non-tonal (English) language speakers. English speakers discriminated the tonal contrasts significantly better in the musical context than in filtered speech, and in filtered sp...
