Create the following circuit components. Your CCT file must contain the following component being tested using switches$/$probs$/$hex keyboard$/$hex display after being saved as a component in your library:

$1.4-$to$-16$ Decoder implemented using a $3-$to$-8$ decoder and $1-$to$-2$ decoder $($c$1-1.$cct$)$;

Requirement: you must implement the $3-$to$-8$ decoder on your own

$2.8-$to$-3$ priority encoder with validity bit $($c$1-2.$cct$)$;

Requirement: your CCT file must show the component tested using a $3-$to$-8$ decoder and HEX keyboard and HEX display

$3.4$ channel $4$bit Multiplexer implemented using the $4$ channel $1$bit Multiplexers $($c$1-3.$cct$)$;

Requirement: your CCT file must show the component being tested using HEX keyboards and HEX

displays
