EEVblog #1081 – Are Bypass Capacitors REALLY needed?

Can a product work without ANY bypass capacitors?
Dave has some fun finding out if “Muntzing” the Gigatron TTL computer works, i.e. removing all the bypass capacitors.
Lots of interesting talk on bypassing, grounding, probing, signal integrity, ground loops, loop area, noise and crosstalk.
TLDR; Don’t remove all your bypass caps, they are important!
