Aliasing, In Theory The Nyquist-Shannon sampling theorem states that, when sampling a signal at discrete intervals, the sampling frequency must be greater than twice the highest frequency of the ...

And understanding aliasing is the first step toward really understanding sampling, and that’s the first step into the big wide world of digital signal processing.

The difference between digital and analog signals may seem straightforward, but there is a ton of nuance that defines the characteristics of the two systems.

Traditional sampling theories require adherence to the Nyquist rate to prevent aliasing; however, many real-world signals possess an inherent structure characterised by a finite number of degrees ...

A signal chain consists of several components, such as amplifiers, data converters, interface, clocks and timing. The purpose of the signal chain is to gather and process data or apply system controls ...
