Dynamic sampling rate

Abstract

A method and device for assuring at least a signal is received undistorted, wherein the method and device including at least one first transducer for receiving acoustic signals in a predetermined frequency band and digitizing said acoustic signals at a predetermined sampling rate, at least one second transducer for transmitting acoustic signals in said predetermined frequency band corresponding to said predetermined sampling rate, an analyzing unit for comparing said transmitted acoustic signals with said received acoustic signals, wherein, the analyzing unit analyzes the quality of said received acoustic signals, detect at least one deviation between said transmitted acoustic signals and said received acoustic signals, and adjust said sampling rate and corresponding frequency band according to a set of predefined frequency bands and sampling rates.
