Time-Domain Analysis

2001
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 ...

Time-Domain Analysis

2017
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.

Time-domain ray analysis

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.

Time Domain Analysis

2016
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 ...
