ABSTRACT:
The invention relates to a method and apparatus for shaping an input signal Sonwhich is input to a multi-stage amplifier arrangement, to provide a definable output signal contour Soff. Individual amplifier stages are controlled by a control signal generated by a pulsed current source of a definable pulse length T. According to the invention, successive amplifier stages are each controlled (switched on) after a definable delay time Δton 1, Δton 2following the preceding stage. Each amplifier stage has an assigned pulsed current source for generating the control signals of definable pulse length T. One such pulse generator respectively is assigned to each current source.
