The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Exemplary Ca2+ signaling microdomains. Cartoon illustration of various microdomains featured in different types of cells, all being artificially integrated in a hypothetical single cell. (1) Cardiac ...

The digital signal controller (DSC) has emerged to handle many of the engineering challenges that previously required both microcontrollers (MCUs) and digital signal processors (DSPs). A hybrid of ...

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 ...

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 ...
