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 ...

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 ...

Here’s what you’ll learn when you read this story: For more than 50 years, scientists theorized that an electromagnetic wave could be reflected temporally—not just spatially. Scientists have been ...
