A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

If you work with digital signals, you know how important it is to avoid aliasing and distortion. These are phenomena that occur when you sample a continuous signal at a rate that is too low to capture ...

Traditionally, undersampling is utilized in communication applications where a range of non-baseband signals sitting above the nyquist frequency are desired to be sampled. The bandwidth of these ...

Abstract: With the development of information technology, the amount of data of the signal acquisition end in high sampling rate fields such as wireless communication and medical imaging based on the ...
