Digital Signal Processing (DSP) was, a few decades ago, a relatively obscure field associated with the mathematics of numerical analysis. As computers have become cheaper and faster, it is now ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

This series is drawn from the course “DSP Made Simple for Engineers.” For more information, see Besser Associates. This article is also available as a PDF Part 2 introduces quadrature (complex) ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

This Design Brief introduces a computationally efficient network that computes the derivative of a discrete time-domain (digital) sequence. While recursive differentiating networks exist, this article ...

Signal processing is a multidisciplinary field concerned with the analysis, transformation, and interpretation of signals—functions that convey information about physical phenomena. At its core, ...
