$2\mathrm{.}1$ Given G$1$ and G$2$ are two enable pins. For the decoder to function, which logic value should

we assign to G$1$ and G$2?$

$2\mathrm{.}2$ In a decoder, basically we select one output $($among all outputs$)$ based on the inputs.

Suppose we set the enable pins correctly, and we set A $=0,$ B $=1,$ C $=0,$ D $=1,$ which output is

chosen?

$2\mathrm{.}3$ The chosen output is high or low based on the IC pinout?

$2\mathrm{.}4$ Given that the output number indicates the decimal value of the inputs, which input $($A or B or

C or D$)$ should be considered the most significant bit?

$2\mathrm{.}5$ Given that the output number indicates the decimal value of the inputs, which input $($A or B or

C or D$)$ should be least significant bit?
