GATE CSE 1992 | Question: 07b
Consider the function $F(n)$ for which the pseudocode is given below : Function F(n) begin F1 ← 1 if(n=1) then F ← 3 else For i = 1 to n do begin C ← 0 For j = 1 to n – 1 do begin C ← C + 1 end F1 = F1 * C end F = F1 end [$n$ is a positive integer greater than zero] Solve the recurrence relation for a closed form solution of $F(n)$.

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.
