Question: A processor has seven interrupt-request lines, INTR1 to INTR7. Line INTR7 has the highest priority and INTR1 the lowest priority. Design a priority encoder circuit

A processor has seven interrupt-request lines, INTR1 to INTR7. Line INTR7 has the highest priority and INTR1 the lowest priority. Design a priority encoder circuit that generates a 3-bit code representing the request with the highest priority. (Ps I can do the truth table but the circuit I have no idea)
