A Bowling Ball Waxing or Buffing machine is used to polish the ball and keeps it glossy $($shiny$).$

The machine starts when user inserts needed coins. In that case the Start input $($S$)$ is set. After two rounds $($states $1$ and $3)$ of spinning the ball $($SB$)$ and waxing $($W$),$

the ball is buffed $($B$)$ then checked to see if it is shiny enough or not. If not $($G is false$),$ heat $($H$)$ is applied and more spinning, waxing and buffing is done. Once the

ball is shiny, the Glossy input $($G$)$ resets the machine, and the process is stopped. The ASM chart is given below. Notice the numbering of the states is in Gray code

format.

Mealy ouputs include?

$1-$B

$2-$H

$3-$H and S

$4-$S and G

Moore ouputs include?

$1-$B$,$ SB$,$ W$,$ H

$2-$SB$,$W$,$ H

$3$H

$4-$B$,$SB$,$W

The B output logical expression is:

$1-$Q$2\text{'}.$Q$1.$Q$0\text{'}.$S

$2-$Q$2\text{'}.$Q$1.$Q$0\text{'}$
