Abstract
The invention relates to a filter unit for filtering multiple pulse signals comprising a number of filter circuits, which are connected in parallel. Each filter circuit comprises an input and an output, wherein the input is configured to receive an amplitude of an input signal and the output is configured to activate an output signal. Each filter circuit has an allocated filter level and further comprises a pulse level detection circuit configured to detect a change of state of a pulse level of the input signal. The change of state comprises a transition from a first pulse level to a second pulse level and if the pulse level corresponds to the allocated filter level of the filter circuit the output of said filter circuit is activated.
