1. A powered surgical system comprising:
an instrument drive unit;
an instrument configured to couple to the instrument drive unit; and
a detection circuit configured to supply an input signal to the instrument and to output, in an asymmetric-in-time hysteresis-in-time manner, an output signal having a first value indicating a connection of the instrument or a second value indicating a disconnection of the instrument, wherein the connection of the instrument is detected within a first interval and the disconnection of the instrument is detected after expiration of a second interval that is longer than the first interval.
