The traditional way of analyzing economic time series views the series as if it were generated by a repetitive process over time. This article shows how a time series can be analyzed in terms of ...

Analytical and experimental background for the fundamental understanding of time and frequency domain signals, required for digital signal processing, vibration, and acoustic signal analysis.

In time domain, it has the effect of interpolating between the samples because multiplication with a rectangular filter in frequency domain is equivalent to convolving with a sinc function in time ...

This tutorial explains the fundamentals of time-, frequency-, and modulation-domain analysis from the perspective of several examples.

One such example is the application of the Fourier transform, which transforms a data set from the time domain into the frequency domain. Yet what is this frequency domain really?
