"This signal goes through two inverter circuits, creating a sharp output."
The two inverter-tubes share a common cathode resistor. This provides positive feedback from the second inverter to the first. The circuit is called a Schmitt trigger:

- raverbashing 9y agoAnd today you get 6 of them in a small package like in the 74XX derived families (74AHC14 for example) And that's when you're doing a not so streamlined circuit, and can't have them inside your ASIC or something, if you can it gets even smaller
- kens 9y agoFootnote 12 in the article goes into details on the Schmitt trigger.
