In this chapter we have consolidated the mathematical developments necessary to relate the physical system and the differential equation describing it. This included the derivation of the impulse response, step response, and convolution integral. These quantities, which are important to the theory of filtering, were shown to be a function of the L.I ...

Heart rate variability can be analyzed by several methods, being time-domain methods the simplest measures that can be obtained from RR intervals series. Numerical indices summarizing the variability of the series are calculated from the RR intervals series. These measures are easily implemented and have low computational cost.

Proceedings of the IEEE, 1970
Time-domain ray analysis is employed in a novel way to explain impulse response waveforms. Examples of reflection from a disk, corner, and paraboloid are discussed and supported by experimental results. It is shown that the reflected waveforms can be readily characterized by superpositions in time of direct, specular, and diffracted rays.

An enhanced strip theory, basically like that described in the last chapter, has been developed and used extensively over recent years for the analysis of planing boat performance and in designing planing power boats. The mechanics of this book now shifts, by both necessity and availability, from semi-analytical to more semi-numerically predicted boat ...

TDAT-time domain analysis tool for EEG analysis
IEEE Transactions on Biomedical Engineering, 1990An interactive design and analysis tool for displaying and quantifying multiple channels of data is presented. The system allows one to easily visualize multiple data channels and simultaneously observe the effects of filters on the data and to evaluate signal detection algorithms.

Robust time-domain frequency analysis
SPIE Proceedings, 1992One domain in which the ordering filters have not appeared is frequency analysis. Simultaneously one must note that the impulse rejection properties of the ordering filters could be very beneficial due to the lack of robustness of the DFT/FFT. Another problem with the DFT/FFT is the ambiguity of the estimate of frequency at a point (frequency ...

IEEE Computer Applications in Power, 1992
The program Power Electronic Circuit Analysis (PECAN), which has been made to handle some power engineering applications not suited for SPICE or EMTP, is discussed. Time functions of voltages, currents, torque, angular speed, power, and other derived quantities can be calculated and plotted on the screen a printer, or a plotter.

This chapter describes numerical integration methods for transient stability analysis. Section 8.1 provides a qualitative justification of the need for numerical integration and describes intrinsic limitations of Lyapunov’s direct method. Section 8.2 describes two common models for time domain analysis, namely the current-injection and the power ...

LLC Resonant Converter-Frequency Domain Analysis or Time Domain Analysis
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020Frequency domain based analysis methods have been widely used for resonant converters due to its simplicity and acceptable accuracy. However, considerable errors would exist when the switching frequency is far away from the resonant frequency, where the circuit currents contain rich harmonics, which cannot simply be neglected.

Optimizing Time-Domain Network Analysis
46th ARFTG Conference Digest, 1995In this work, we demonstrate how changes in sample density, time-window size, and waveform averaging affect the accuracy and acquisition time of calibrated time-domain network analysis. One of the key results from this study is that accuracy can be enhanced by eliminating the incident step-edge signal from the time-domain reflection waveform before ...
