The measurement algorithms applied in power quality measurement systems are based on Fast Fourier Transformation. That one-dimension frequency analysis is sufficient in many cases. However, to illustrate the character of the signal in a more comprehensive manner, it is crucial to represent the investigated signal on time-frequency plane. There are a lot of time-frequency representations (TFR) for presenting measured signal. The TFR: Short-Time Fourier Transformation (STFT), Smoothed Pseudo… Expand
Pre-Processing and Classification of Cough Sounds in Noisy Environment using SVM
TLDR
A 'Fourth Order Butterworth High Pass Filter (FOBHPF) is applied at the pre-processing stage followed by features extraction and classification using SVM, and performance evaluation during the simulations has carried out using Signal-to-Noise Ratio (SNR) parameter at output of thePre- processing stage and accuracy parameter at the end of classification stage.

Providing a Visual Understanding of Holography Through Phase Space Representations
TLDR
This tutorial-style paper will showcase the S-method, which is both a PSR that can be calculated directly from any given signal, and that allows for a clear visual interpretation, and the power of space-frequency analysis in digital holography. Expand
A signal processing approach for the diagnosis of asthma from cough sounds
TLDR
Time-frequency analysis techniques, specifically Wigner distribution in addition to wavelet transform to analyse cough signals, are used and the results are competitive to the best existing algorithms in the literature. Expand
