摘要

The digital filter arrangement has signal input (2) and a signal output (3) with a first signal path arranged with a first digital filter (5). There are at least two adjustable filter ranges switched in between the signal input and output. The delivery of an adjusting signal is made by arranging the signals at the input side resting against the adjusting entrance (51). There is a second signal path connected with the signal input and exhibits a second digital filter (6) and a circuit gate (7), which are at the signal output with the adjusting entrance of the first filter. The first signal is delivered to a first exit (62) and a second signal is delivered to a second exit (61). The first entrance (76) is connected with the first exit and the second entrance (75) is connected with the second exit. Independent claims are also included for the following: (A) Use of the digital filter arrangement; and (B) Method for the control of switching time in a digital filter.
