Microvolt T-wave alternans (TWA) is among the important risk stratifiers for sudden cardiac death, having significant prognostic ability. A new detection theoretic technique, called template matched-filter detector (TMFD), is proposed for TWA detecti

If the signal is not Gaussian, then the power spectral density (PSD) approach is insufficient to analyze signals and we resort to estimate the higher order spectra of the signal. However, estimation of the higher order spectra is even more time consu

Power Spectral Density (PSD) computed by taking the Fourier transform of auto-correlation functions (Wiener-Khintchine Theorem) gives better result, in case of noisy data, as compared to the Periodogram approach in case the signal is Gaussian. Howeve

The most widely used methods for time- frequency analysis belong to Cohen’s class of spectrogram estimators. Wigner–Ville distribution (WVD) and multiwindow time -frequency analysis are the most popular techniques. One serious limitation of Wigne

Instantaneous frequency is defined as the average of the frequencies present in the signal at a particular instant. To estimate instantaneous frequency, a window of N samples is taken at each time instant. In such techniques, N needs to be large enou

The classical Cooley-Tukey fast Fourier transform (FFT) algorithm has the computational cost of O(Nlog2N) where N is the length of the discrete signal. Spectrum resolution is improved through padding zeros at the tail of the discrete signal, if (p -1
