1. A circuit for shaping an input signal which is input to a multi-stage amplifier arrangement, to provide a definable output signal spectrum, comprising:
a plurality of individual amplifier stages coupled in series, each having an associated pulsed current source that impresses a current corresponding to a definable pulse length upon a respective one of the amplifier stages for sequentially switching on all of the individual amplifier stages; and
a plurality of independent pulse generators, each of which is operatively connected to a respective one of said pulsed current sources to generate control signals that independently control the associated individual amplifier stages to avoid creation of non-linear distortion during switching operations of the plurality of individual amplifier stages.
