In undersampling applications, such as wideband receivers, cellular base stations, and communications receivers, the undersampled signal has a relatively low-frequency bandwidth—with the help of the ...

Bravo to Harry Nyquist and Claude Shannon! In the 1920s, these gentlemen created the now-well-known Nyquist theorem, which states that when sampling a signal at discrete intervals, the sampling must ...

In Specifying & Creating Data-Acquisition Systems, Part 3, I noted unwanted high-frequency signals could alias or "fold" into the signals you plan to measure. Anti-alias filters can remove those ...

When asked about the biggest challenge in today’s bioprocessing, Sandy Williams, PhD, a biomedical engineering expert at Scientific Bioprocessing (SBI) in Pittsburgh who focuses on regenerative ...

Is undersampling really as bad as they say in astrophotography? In this video, we break down what undersampling means, its pros and cons, and when it might actually work to your advantage. Perfect for ...
