A function $F$ is defined such that it equals 1 when a 4-bit input code is equivalent to any of the decimal numbers $3,6,9,12$, or 15 . Function $F$ is 0 for input codes $0,2,8$, and 10 . Other input values cannot occur. Use a Karnaugh map to determine a minimal expression for this function. Design and sketch a circuit to implement this function, using only AND and NOT gates.
