Part $1$: $1-$Bit ALU

Design a $1-$bit ALU suing to perform logical and, logical or and addition.

You need to use a full adder of two half adders and an OR gate.

Your file needs to have three circuits.

Half$-$Adder

$1-$bit Full$-$Adder

$1-$bit ALU

Part $2$: $4-$Bit ALU

Design a $4-$Bit ALU using $41-$Bit ALUs.

Your file needs to have three circuits.

Half$-$Adder

$1-$bit Full$-$Adder

$1-$Bit ALU

$4-$Bit ALU.

All of the input bits should be together and use a splitter.

All of the output bits should be together and use a splitter.
