Abstract
An electronic apparatus has a transmitter arranged to transmit an acoustic signal. It also has a receiver, for receiving acoustic energy comprising a reflection of the acoustic signal from an input object. It generates an electronic received signal from the received acoustic energy. The apparatus has processing means arranged to: (i) analyze at least a portion of the received signal to determine a linear combination of basis functions which represents an interference component in the received signal; (ii) use the determined linear combination to attenuate interference within the received signal, to give a post-attenuation signal; and (iii) use the post-attenuation signal to determine a user input to the electronic apparatus.
