The smallest AND gates using Comparators (read description)
I have searched for this particular use case of comparators, but nobody called it as the NIMPLY Gate. Thanks to Kebabisoos from ORE, I got to know that the NIMPLY gate even exists.
However, I have been using it for my builds for any kind of AND gate and it's really really convenient for various cases.
NIMPLY Construction:
Comparator in subtract mode with side input and back input giving either same non-zero signal strength or zero.
NIMPLY looks like: A AND (NOT B). One simply needs to use another NOT gate on the side input in order to make the setup an AND gate.
(This post might be obvious to many, but it had to be documented because this is an extremely niche practice in logical redstone)
