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.

Most embedded engineers writing firmware have used some sort of digital filters to clean up data coming from various inputs such as ADCs, sensors with digital outputs, other processors, etc. Many ...

Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio ...

The design of finite impulse response (FIR) filters remains a cornerstone of digital signal processing, with ongoing efforts to refine both the algorithmic and hardware aspects of their implementation ...

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 ...
