GATE1992-04-b
A priority encoder accepts three input signals $\text{(A, B and C)}$ and produces a two-bit output $(X_1, X_0 )$ corresponding to the highest priority active input signal. Assume $A$ has the highest priority followed by $B$ and $C$ has the lowest ... none of the inputs are active the output should be $00$, design the priority encoder using $4:1$ multiplexers as the main components.
