Abstract
A channel filter () with a variable pass bandwidth has a first low-pass filter () on the input side and is driven by a means () for controlling the pass bandwidth as a function of the adjacent channel interference. A first input of the control means () is connected to the first low-pass filter (), and a second input is connected to a bandpass filter () which is connected in parallel with the channel filter (). The signal path which contains the low-pass filter () contains a means () for removing a DC signal component or DC component.
