An improved stable approach monitor (SAM) system provides an audible advisory to a pilot when an aircraft is on a final landing approach.

Feedback receiver for antenna tuner calculations
Some embodiments of the present disclosure relate to a feedback receiver comprising a threshold comparator configured to determine if the amplitude of a baseband signal is within a selection corridor (e.g., defined by an upper and lower threshold value).
