Abstract (en)
[origin: WO0191309A2] A device and method are disclosed, whereby the normally complicated and difficult frequency determination is achieved by simply arranged and executed measures, namely by means of larger, smaller and/or equal comparisons and a counting of certain events. The invention further relates to arrangements whereby the noise signal level, or the influence thereof on the verification to be carried out is reduced.
