摘要: The invention relates to a method for tuning filter (5). has at least one variable time constant, by which the location of pass band (pc) said can be changed. In method, reference signal is inputted in (5), and frequency changed, and/or constant (5) also comprises steps measuring strength output determining, on basis measurement
