1. Find the minimum output expression for circuit of figure below and draw logic circuit. A

2-17 Draw the logic diagram corresponding to the following Boolean expressions without sim- plifying them: (a) BC' + AB + ACD (b) (A + B)(C + D)(A' + B + D) (c) (AB + A'B')(CD' + C'D)

Rebuild the following logic circuits with the minimum possible number of logic gates and under the following conditions: Use only the AND and OR gates with 2-inputs. You can also use any number of NOT gates. f2=abc+abd+a'cd+b'cd

Combinational logic circuits have outputs that are entirely dependent on the inputs of the circuit.

1. Design a combinational logic circuit with three inputs A, B and C and one output X. When only one input is 1, output is 1. When none of input is 1, output is also 1. Otherwise, output is 0.
