ABSTRACT:
A method and device for reducing error components of a multi-channel modulator. The method comprises the steps of inverting substantially half of the channels of a modulator, and reducing error components between said inverted channels and said non inverted channels by inductive and/or capacitive summing. The method is especially suitable for synchronized pulses and similar signals to be modulated.
