How Logic Gates Work

The Learning Circuit **|** element14 presents **|** Project Videos | VCP Biography: Karen

Back on the Ben Heck Show, a viewer requested a real-life build of the game from Jumanji. Since magic isn’t real, the team decided to make a game based on logic gates. After spending months helping Ben try to work out their game, “Logic Bomb”, Karen got a taste for digital logic using logic gates and has been itching to get back to the tricky subject that continued to stump her. This episode covers 7 types of logic gates: NOT, AND, NAND, OR, NOR, XOR, and XNOR. Using truth tables and analog circuits, Karen tries to break down the logic to help you understand the literal ins and outs of each type of logic gate.

Hey everyone,

There's a slight error at 5:52. I'm talking about an XOR gate, but the gate image on the left is an XNOR. The truth table is correct though. So please listen to what I say and ignore the symbol…

Good job presenting basic logic.

It is nice for beginners but addition of FAN IN, FAN OUT, Propagation delay should also be included.
