a$)$ Given the Boolean function $f(A,B,C,D)={\displaystyle \underset{?}{\overset{?}{}}}m(0,2,3,6,8,9,13,14)$;

design a $8$ to $\frac{1}{M}Ux.$

b$)$ A demultiplexer $($DMUX$)$ is a combinational logic circuit with one input line;

$2^n$ output lines and $n$ select lines. It is also called data distributor. It routes the

information present on the input line to any of the output lines.

Design a $1$ to $4$ Demux with an input line HIGH.

c$)$ Define and draw a classical block diagram of a Sequential logic circuit.
