Q$1)$ Using $3$ bit comparators and ary required digital componnrts, design a circue that compares three numbers. Each number is $3$bes. The larjest fumber will be displayed on $7$ segment display. $($use block diagrams of the comparalors$)$

Q$2)$ Using JK thp fops, design a counter that counts $0-2-4-6$ and back to zero if the input is $1.$ And it will count $0-6-4-2$ and back to $0$ if the irput is $0.$ The count will be displayed an $7$ segment display.

Q$3)$ The bank uses a queue system to ensure the privacy of its customers. Each customer gets a number and wats for hisher turn.

Each teller announces the customer number which will be serviced using tavo serven$-$segment displays: one to show the customers number thd the other to show the lellor's desk number.

Each teller has

$1-$a push button to call the next customer

$2-$A seven$-$segment display to display the customer number.

$3-$ A unique desk number

The system has

T$-$ A counter

$2.$ push buttens

$3-$ One main seven$-$segment display to show the customer's rumber

$4-$ One main seven$-$segment display to show the teller's number.

$5-$ One seven$-$segment display for each teller to show the customer's number.

When a teller presses the push button

The counder increases by one

The content of the counter is displayed on the teller $7-$segment display.

The content of the counter is displayed on the main $7-$segment display

The leller number who pressed the button is displayed on the main $7-$segnient

display associated with the teller desk number

Suppose the bank has $3$ tellers, the customers' numbers are from $0-9$

you have $5$ Seven$-$segment displays and one counler.

Use a block diagram in your design

Show the gate$-$level design for the counter.
