If a,b,c,d are inputs to a gate and x is tis output then, as per the following time graph, the gate is:
The output of an AND gate is connected to both the inputs of a NOR gate, then this circuit will act as a
The following figure shows a logic gate circuit with two inputs A and B and the output C. The voltage wavefront of A, B and C are as shown in the figure. The logic circuit gate is
