About this episode
In this episode we demystify linear feedback shift registers (LFSRs): tiny digital circuits that generate long, pseudo-random sequences. We’ll unpack how Fibonacci and Galois LFSRs work, where they show up—from GPS and USB to Bluetooth and chip testing—and why their linearity is both a powerful tool and a security risk. A window into the paradox of deterministic rules producing seemingly random behavior that underpins much of our digital world.
