Information theory & signal processing Videos Recommended on Hacker News (43)

Information theory & signal processing is one of the 150 topics Hacker News readers organize their video recommendations around. These 43 videos each earned real recommendations in real HN threads between 2009 and 2026 — 129 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.

Information theory and signals: entropy, Claude Shannon, compression, error-correcting codes, Fourier transform, signal processing, sampling, digital audio and video theory.

Why HN keeps sending people here — on But what is the Fourier Transform? A visual introduction.: “this was the first thing that ever really made sense to me” — an HN commenter, 2020.
