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 Structural Analysis of Speech
2003This paper deals with an auxiliary speech signal parametrisation method based on structural analysis of speech signal in time domain. The method called TIDOSA (TIme-DOmain Structural Analysis) grounds in analysing the "shape" of incoming waveform peaks. The whole input acoustic signal is transformed into a sequence of peak shape class indices.

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 ...

Time-Domain Analysis of the Electrocardiogram
2019The electrocardiogram (ECG) is an affordable and well-studied biosignal, which has a wide presence in clinical research and practice, especially as a frontline diagnostic tool that measures the evolution of the electrical activity of the heart, with characteristic morphologies for atrial and ventricular activity, depending also on the position of ...

In the frequency domain discussed in the previous chapter, a spectral approximation is used for an arbitrary second-order stationary time series ..., y -1, y 0, y 1,.... In the traditional approach, the variance components in the spectral approximation will be nonzero, thus there is little chance of developing a parsimonious model.

Analysis of accumulated timing-jitter in the time domain
IEEE Transactions on Instrumentation and Measurement, 1998This paper deals with the effects of accumulated timing-jitter on the signal-to-noise ratio (SNR) of real sine waves. Such a problem was recently investigated by the author, using the discrete-Fourier method. However, the frequency-domain analysis has some limitations due to the fact that some of the accumulated timing-jitter noise power, found at the ...

Time-domain analysis of the Savitzky–Golay filters
Digital Signal Processing, 2012This paper proposes a time-domain method to analyze the estimation performance of Savitzky-Golay (SG) filters, which includes estimation performance of SG smoothing filters and SG differentiation filters. An estimation error bound is given and its qualitative properties are analyzed.

Time-domain macromodels for VLSI interconnect analysis
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1994This paper presents a method of obtaining time-domain macromodels of VLSI interconnection networks for circuit simulation. The goal of this work is to include interconnect parasitics in a circuit simulation as efficiently as possible, without significantly compromising accuracy.

Dispersion and time-domain analysis
1999This chapter discusses how the mixing process affects the temporally dispersive properties of materials. The time variation of the electromagnetic phenomena under consideration is very simple. It is sinusoidal, and the frequency of the wave variation is a measure for the time derivatives that are needed in Maxwell equations.
