Question one

Compare the last digit $($from right$)$ of your registration number with number five

by using the $4$ bit number comparator IC show the output of the comparator on led

as indicator: r$]($my registration number is $202010984)$

if it's greater than five add number six to the last digit by using $4$ bit adder IC and

show the outputs on Digital Hex Display $7-$ Segment, then make the correct

correction in order to the display the sum on $7-$ segment in BCD code with the aid

of a $4-$bit binary adder and comparator.

if it's less than five add number nine to the last digit by using $4$ bit adder IC and

show the outputs on Digital Hex Display $7-$ Segment, then then make the correct

correction in order to the display the sum on $7-$ segment in BCD code with the aid

of a $4-$bit binary adder and logic gate.

if it's equal five add number seven to the last digit by using $4$ bit adder IC and

show the outputs on Digital Hex Display $7-$Segment, then make the correct

correction in order to the display the sum on $7-$ segment in BCD code with the aid

of a $4-$bit binary adder and comparator.
