Question $2.$ An encoder, as discussed in class, makes the assumption that only one input

line is active at a time. A priority encoder allows multiple inputs to be active, and outputs

the binary representation for the highest priority line input currently active. Assume lower

binary numbers have higher priority. For example, if lines $2,3,$ and $7$ are active, the output

will be $0$ b$010("2").$ Design a $8-$to$-3$ binary encoder, with priority in binary sequence $($i$.$e$.$

input line $0$ has higher priority than input line $1$ etc $).$ There should also be an "active" out$-$

put which is $1$ when any input line is active, and $"0"$ when all input lines are $0.$ If all input

lines are $0,$ the output lines other than the "active" output are "don't care". Implement

and verify the circuit.
