Digital Logic Lab

Wire real logic circuits, watch signals propagate and derive truth tables, from gates to flip-flops, counters and an ALU.

AND: Output 1 only if both inputs are 1

Testing G1 on the board; changing the type keeps its wires.

Input A ← A

Input B ← B

Output

A = 1 · B = 0

Y = A·B

Inputs

The truth table shows all possible outputs for each combination of inputs; the highlighted row is the gate right now.
