Time-Frequency Domain for BCG Analysis
2018 International Conference on Computer and Applications (ICCA), 2018The aim of this paper is to explore the time-frequency domain for the analysis of Ballistocardiogram (BCG) signals. The BCG signal reveals the mechanical activity of the heart by representing the propagated vibrations caused the ejection of blood into the arteries.

Identification and Error Analysis in Frequency Domain
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006The identification algorithm and error analysis are considered in frequency domain by using discrete Fourier transform and spectral analysis. A simple algorithm to estimate the signal spectra is proposed and the property of the estimation is analyzed. The feature of the proposed algorithms is that they can be implemented very easily and the information

Frequency domain analysis of rotational motion
Multidimensional Systems and Signal Processing, 1993Frequency domain analysis of moving imagery is quite informative with respect to spectral estimation and coding techniques based on short-time Fourier transform and wavelet transform. The frequency domain analysis for translations [see the first and the third author, IEE Trans. Pattern Anal. Machine Intell. 15 (1993) and the first author and \textit{G.

A Frequency Domain Analysis of Learning Control
Journal of Dynamic Systems, Measurement, and Control, 1994The convergence of learning control is traditionally analyzed in the time domain. This is because a finite planning horizon is often assumed and the analysis in time domain can be extended to time-varying and nonlinear systems. For linear time-invariant (LTI) systems with infinite planning horizon, however, we show that simple frequency domain ...

The analysis of electrical signals is a fundamental problem for most engineers. As we have seen, even if the basic problem is not electrical, the parameters of interest are usually changed from pressure, force, temperature etc. into an electrical quantity by means of transducers.

Although the differential equation is a basic system description, obtaining this equation can be tedious and time-consuming. Consequently for a time-invariant system this approach is avoided in practice, except in special cases. The Fourier and Laplace transforms offer an alternative approach for characterizing and analyzing these systems. Insight into
