Filter bank design forms a cornerstone of modern digital signal processing, enabling the decomposition of signals into multiple frequency subbands for both analysis and synthesis. Recent advancements ...

In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Three ...

Variable fractional delay (VFD) filter design has become increasingly significant in digital signal processing, offering the flexibility to delay signals by non-integer amounts. This technology is ...

Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.

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 ...

There’s an old saying: Tell me and I forget, teach me and I may remember, involve me and I learn. I’m guilty of this in a big way — I was never much on classroom learning. But if I build something or ...

Modern SDRs evolve from configurable platforms into intelligent wideband sensing systems combining high dynamic range, ...

A digital signal processor is an IC or IP core designed to process signals digitally with efficiency. Analog signals are converted to digital via an analog-to-digital converter before being processed ...

How analog signal engineering is performed, in broad strokes. What are the component-selection considerations for new designs? What are VFAs and how are they used? Analog signal engineers specialize ...
