$ C D


Solution -
The logic circuit shown in given figure has four inputs A, B, C and D. Forming a logic circuit with a combination of OR and AND gates.
Gate-1: (OR GATE)
Two inputs of logic gate - 1 is given as A and B.
The inputs A and B are connected to OR gate producing an output of A+B .
Gate-2: (OR GATE )
The logic gate - 2 is same as Gate 1 only difference is it has input C and D
The inputs C and D are connected to OR gate producing an output of C+D .
Gate-3: (AND GATE)
The logic gate-3 has two inputs i.e A+B and C + D . One input is obtained from the output of OR gate-1 and the second input is obtained by same second OR gate 2 .
The inputs A+B and C+D are connected to AND gate producing an output of Y= (A+B) . (C+D).
