Design a combinational circuit with three inputs and one output.

a$)$ The output is $1$ when the binary value of the inputs is less than $3.$ The output is $0$ otherwise.

b$)$ The output is $1$ when the binary value of the inputs is an even number.

Design a combinational circuit with three inputs, $x,y,$ and $z,$ and three outputs, $A,B,$ and $C.$ When the binary input is $0,1,2,$ or $3,$ the binary output is one greater than the input. When the binary input is $4,5,6,$ or $7,$ the binary output is two less than the input.

Design a combinational circuit that converts $4$ bit BCD input to $8,4,-2,-1$ code.

The adder$-$subtractor circuit has the following values for mode input $M$ and data inputs A and B$.$ In each case, determine the values of the four SUM outputs, the carry $C,$ and overflow $V.$
