Abstract

The present invention relates to a system (100) for determining frequency of a signal, comprising: an input (10) for receiving a signal; a delaying means (20) comprising a plurality of first delay cells (21), connected to the input (10) for receiving the signal, and delaying the signal by a first predetermined period to produce delayed signals; and an evaluating means (30) comprising a plurality of capturing means (32) connected to the delaying means (20) for capturing the delay signals and determining frequency of the signal; characterized in that the evaluating means (30) further comprises: a second delay cell (31) connected to the input (10) and at least a corresponding capturing means (32) for delaying the signal by a second predetermined period; a detector (33) connected to the plurality of capturing means (32) for receiving the captured delayed signals and detecting a predetermined pattern; and a processor (34) operating with the detector (33) for determining frequency of the signal, wherein the signal is a clock signal.
