This abstract first appeared for US patent application 20250004697 titled 'SYSTEMS AND METHODS FOR DETECTION STATUS OF INTERCOM TERMINATION
Original Abstract Submitted
systems and methods for detecting detect termination status in an audio communication system, wherein termination status indicates whether exactly one termination circuit is part of the audio communication system, are disclosed. exemplary implementations may: accept an input voltage, by a voltage-controlled current source that includes and drives a resistive load; generate an ac voltage used as an input voltage for the current source; connect a first set of one or more filters to the output of the current source that generate a first analog output signal; connect a second set of one or more filters to the resistive load that generate a second analog output signal; determine a ratio of the first and second analog output signals and use it to determine the termination status.
