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 ...
