Abstract
A digital predistorter comprises a module (J) for producing a counteracting signal V.sub.m1 for combination with the input signal of a power amplifier to correct the output of the amplifier for distorting memory effects within the amplifier. The module (J) produces the counteracting signal V.sub.m1 by convolving (see FIG. 6) non-linear functions of the input signal with impulse response characteristics related to the memory effects being corrected.
