1. A method of detecting one or more touch events on a capacitive touch sensitive device comprising;

  • configuring a plurality of channels, each channel corresponding to the capacitive touch sensitive device;

    sampling each channel in the plurality of channels according to a randomization algorithm that includes performing multiple sampling cycles, each sampling cycle including sampling each channel in the plurality of channels;

    for each channel, calculating a channel capacitance using sampled data; and

    determining one or more touch events from the channel capacitances calculated for the plurality of channels.
