In a digital logic circuit, two inputs A and B are each passed through a separate NOT gate. The output of the first NOT gate is connected to the cathode of an ideal diode D₁ , and the output of the second NOT gate is connected to the cathode of an ideal diode D₂ . The anodes of both diodes are tied together and connected to a +5 V supply (Logic 1 ) through a resistor R . The final output Y is taken from the common an

Step-by-step solution

The inputs A and B pass through NOT gates, so the signals reaching the cathodes of D₁ and D₂ are A and B , respectively. In the diode-resistor circuit, if either cathode is at 0 V (Logic 0 ), the corresponding diode becomes forward-biased. This pulls the common anode node Y down to 0 V (Logic 0 ). If both cathodes are at +5 V (Logic 1 ), both diodes are reverse-biased. No current flows through the resistor R , and the node Y remains at +5 V (Logic 1 ). This behavior corresponds to an AND gate for the inputs at the
