Abstract
Detecting a location of a touch input on a surface of a propagating medium is disclosed. A transmitter coupled to the propagating medium emits a signal. The signal is received using a receiver coupled to the propagating medium. The receiver is configured to receive the signal from the transmitter to at least in part detect the location of the touch input as indicated by an effect of the touch input on the signal. Spectral control of the signal is performed.
