Evaluate the following numerical arithmetic expression using

stack operations by first writing it into reverse Polish notation.

$(3+4)[10(2+6)+8]$A$).$ Propose a hardwired control unit $($block diagram$)$ consisting of

IR$,$ two decoders, a sequence counter, and logic gates. Also draw a

timing diagram assuming that sequence counter is cleared to $0$ at

time $T_3$ if decoder signal $D_2$ is active.
