Abstract
A nonlinear frequency domain filter serving for the suppression of unwanted signals which are superposed on a wanted signal variable in a given frequency range. The frequency domain filter comprises linear transmission members and a dead-zone member. With the filter, the zero point of the dead-zone member, to which the input signal to be filtered is supplied, follows proportionally the output signal of a pass-band filter connected in parallel with the dead-zone member. Further, the output signal of the pass-band filter is added to the output signal of the dead-zone member.
