Abstract
This disclosure generally provides embodiments to reduce the likelihood that an input device fails to detect an interfering signal when performing interference detection using interference bursts that are phase offset from sensor bursts used to perform capacitive sensing. In one embodiment, the input device adjusts the frequency of the interference bursts instead of using interference bursts with the same frequency. Doing so adjusts the phases of the interference bursts relative to each other such that even if one of the interference bursts is aligned with the interfering signal in a manner that the signal is not detected, an interference burst with a different frequency has a different alignment relative to the interfering signal. The measurements acquired by the differently aligned interference burst can be used to detect the presence of the interfering signal.
