Abstract
Examples are disclosed herein that relate to reducing noise in received signals. An example provides a method comprising receiving, via one or more electrodes of an input device, a capacitive signal, for each of two or more reference sequences designed for a respective capacitive signal condition, correlating the capacitive signal with the reference sequence, and identifying a particular one of the two or more reference sequences that produced a highest noise immunity when correlated with the capacitive signal. The method may further comprise correlating the identified reference sequence with a subsequent capacitive signal to thereby receive information in the subsequent capacitive signal regarding an input device condition.
