ABSTRACT:
A method for detecting an information signal, tone and/or a phase change of a tone in one or more signals which contain inter alia this information signal or this tone, is characterised in that each signal is divided into segments (blocks), in that only a selection of the blocks are further processed for detection, whereas the blocks which have not been selected are not processed further, wherein the signal in the blocks is made available for further processing in the form of samples of a signal in the time domain, in that the blocks are subjected to a transformation, for example a transformation from the time domain to the frequency domain, in order to produce at least one output value, and in that a decision regarding detection is made with the aid of at least one output value of the transformation.
