ABSTRACT:
In a method of generating a pulse-shaped transmitted output signal having a definable pulse shape in a multistage amplifier arrangement, the course of the “pulse top” (upper edge) of the transmitted signal is determined by control signals at the amplifier stages. The control signals of the amplifier stages are definable such that the control signal of an amplifier stage in each case comprises a number of pulse sections of a predefinable frame pulse. The tops of the pulse sections each having a predefinable constant gradient. A predistortion is introduced into the control signals in this manner, having a course which offsets distortion of the pulse top which results when no predistortion is used.
