In the circuit shown, inputs A and B each control a diode into a common node, which is tied through a resistor to V and also drives an LED (Y) to ground: the node — and the LED, which lights when the node is LOW — is pulled LOW whenever at least one of A, B is LOW (0), and goes HIGH (LED off) only when both A and B are HIGH (1). This gives the truth table A,B Y: 0,0 1; 0,1 1; 1,0 1; 1,1 0. The correct Boolean operation represented by this circuit is:
