Classification: CPC G  H | IPC H

Claim 9:
10. A method for correcting an input signal, comprising:
receiving the input signal, the received input signal comprising a time series of input values representing a received ultrasonic signal,
matching a series of template values to the series of input values by warping the series of template values and the series of input values relatively to each other so as to assign one or more template values to one or more input values,
wherein the series of template values represents an approximation of a noise signal that is expected to be comprised in the input signal,
obtaining a series of corrected input values based on a mismatch between the input values and their respective assigned template values;
providing a corrected signal based on the series of corrected input values; and
wherein the time series of input values and the series of template values cover a time span of a ringing of an ultrasonic transceiver after transmitting an ultrasonic signal that results in the received ultrasonic signal.
