Logic gates: AND, OR, NOT
A revision video from Computerphile which covers the three basic logic gates: AND, OR, and NOT. The video includes truth tables, logic gate symbols, and the different notations that are used to denote 'AND' and 'OR'.
This video starts by recapping the truth table for an exclusive-OR (XOR) gate, and then goes on to show how its properties can be used to help create a half-adder in conjunction with an AND gate. The video helps demystify the concept by building up the half-adder and explaining with examples why an additional gate is needed.
