engineering recuitment GATE ECE 2023-24 Test Series Digital Electronics Combinational Circuits Multiplexer
The propagation delays of the XOR gate, AND gate, and multiplexer (MUX) in the circuit shown in the figure are 4 ns, 2 ns, and 1 ns, respectively.
If all the inputs P, Q, R, S, and T are applied simultaneously and held constant the maximum propagation delay of the circuit is
1
6 ns
2
7 ns
3
3 ns
4
5 ns
