Abstract |
AB |
[EN] A digital filter having (30) an input and an output and comprising a first FIR-filter (31) having m stages and a second FIR-filter (32) having n stages and an input connected to the input of the digital filter, wherein m and n are positive integers and n is greater than m, and wherein the output of the digital filter is selectively connectable through a switch (33) to one of an output of the first FIR-filter and an output of the second FIR-filter in accordance with a filter selection signal. The digital filter further comprises an input delay buffer (34) connected between the input of the digital filter and an input of the first FIR-filter and having k stages, wherein k is a nearest integer from (n - m)/2. |
