| Zusammenfassung: | This invention relates to a method as well as a computer product, system and device for controlling the frequency range of an emitted ultrasound signal from a device. The device includes a number of acoustic transducers, the method including the step of generating an electronic signal within a predetermined frequency range in the time domain, convolving the said electronic signal with a time envelope function thus providing an emission signal. The time envelop function is calculated based on a transformation of the predetermined frequency range of the emitted signal into the time domain, the emitted acoustic signal being generated by the emission signal. |
