As part of an aircrafts functional monitoring system, a circuit is required to indicate the status of the
landing gears prior to landing. A green LED display turns on if all three gears are properly extended
when the “gear down” switch has been activated in preparation for landing. A red LED display turns
on if any of the gears fail to extend properly prior to landing. When a landing gear is extended, its
sensor produces a LOW voltage. When a landing gear is retracted, its sensor produces a HIGH voltage.
Implement a circuit to meet this requirement.
