Abstract
A method of removing an electric crosstalk contribution is disclosed. This crosstalk exists in a monitoring signal from a monitored electro-mechanical transducer in a device comprising a plurality of electro-mechanical transducers which are driven by actuation signals so as to produce acoustic waves in an acoustic frequency range. The method comprises the steps of: (a) applying an actuation signal to at least one of the transducers other than the monitored transducer; (b) detecting the monitoring signal in a high frequency range outside of the acoustic frequency range; (c) deriving, from the detected monitoring signal, a number of parameters that characterize the electric crosstalk; and (d) using said parameters to calculate the electric crosstalk contribution in the acoustic frequency range.
