$3.$ Using two $(2)$ of the following decoders and any number of OR and NOT gates, implement segment a and segment g from a base$-8$ seven segment display driver. Use Table $2\mathrm{.}6$ on page $36$ of our text. Notice that because you only count to $7,$ you can ignore $\backslash ($ W $\backslash )$ and all rows past $111.$

A $2-$to$-4$ active$-$low enabled, active$-$high output binary decoder.

Your driver should have the illustrated inputs $\backslash ($ X$,$ Y$,$ Z$(0\mathrm{.}5\backslash )$ Points$)$ and only the outputs $\backslash ($ a $\backslash )(0\mathrm{.}5$ Points$)$ and $\backslash ($ g $\backslash )(0\mathrm{.}5$ Points$).$

Please provide as much details as possible
