A non-linear circuit having a transfer characteristic which is adjustable per amplitude segment of an input signal (Yi) includes a segmenting circuit (11 . . . 15, 21 . . . 25) for obtaining a plurality of amplitude segment signals (Y1 . . . Y5) from the input signal (Yi), and a non-linear segment amplifier circuit (31 . . . 35) coupled to the segmenting circuit (11 . . . 15, 21 . . . 25) for separately multiplying segments (Y1 . . . Y5) of the input signal (Yi) by respective segment gain factors (HM1 . . . HM5) in dependence upon a common gain factor (HMa) derived from the segment gain factors (HM1 . . . HM5) and on the basis of the amplitude segment signals (Y1 . . . Y5) for supplying a signal (Y''s) which is adjustable per amplitude segment of the input signal (Yi). The non-linear circuit may also include an output circuit (37, 39) coupled to the non-linear segment amplifier circuit (31 . . . 35) for supplying an amplified output signal (Yhm), the amplification of which, with respect to the input signal (Yi), being adjustable per amplitude segment of the input signal (Yi).
