Signal processing devices normally filter the signal to reduce noise. Any filtering is likely to eliminate useful components of the signal too. A device for and method of signal processing is disclosed, wherein intrinsically clean signal cycles are selected for reproduction so that the processed signal retains components of all frequencies. A system that uses the disclosed device and the method for processing periodic physiological signals is also disclosed.

Processing of periodic physiological signals

This method for analysing the sounds of body fluid flows includes:&#x2014;simultaneously acquiring () sounds from various locations of a body;&#x2014;identifying () the points of maximum sound intensity (PMIs) of the acquired sounds for each acquisition instant;&#x2014;determining () the source locations of the acquired sounds; and&#x2014;determining () the sound radiation patterns of the acquired sounds. A corresponding device, system and program perform this method.
