Capacitive sensing using non-integer excitation

A method for capacitive sensing comprising:

• concurrently driving a first transmitter electrode with a first transmitter signal and a second transmitter electrode with a second transmitter signal, wherein the first transmitter signal is based on a first digital code and the second transmitter signal is based on a second digital code, and wherein the first digital code and the second digital code each comprise at least one non-integer multiple;
• receiving a plurality of resulting signals using a plurality of receiver electrodes, the plurality of resulting signals comprising effects of the first transmitter signal and the second transmitter signal;
• and
• determining positional information based on the plurality of resulting signals.
