Apparatuses and methods of frequency hopping algorithms are described. One method listens to a noise level on multiple electrodes of a sense network at multiple operating frequencies. The method then selects one of the frequencies with a lowest noise level for scanning the electrodes to detect a conductive object proximate to the electrodes.
