Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Editor’s note: In this Design Idea (DI), contributor Bonicatto designs a digital filter system (DFS). This is a benchtop filtering system that can apply various filter types to an incoming signal. The ...

This application note presents the MLX90614 on-chip digital signal filters focusing on the on-chip signal-filtering feature part of the integrated circuit. It also describes the filter configuration ...

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 ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

Every modern computer has a microprocessor in it, but not many have a digital signal processor (DSP). Since the CPU is a digital device, it clearly processes digital data, so you might wonder what the ...

We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, ...
