Abstract
Iterative pre-conditioning of an electrical signal for supply to an amplifier, comprising: a first pre-conditioning iteration comprising limiting the amplitude of the electrical signal to produce a limited signal; generating a difference signal for subtracting the electrical signal from the limited signal; and generating an output signal by subtracting the difference signal from the limited signal; at least one further iteration comprising the steps of: Limiting the amplitude of the output signal of the previous iteration to produce a subsequent limited signal; generating a subsequent difference signal by subtracting the electrical signal from the subsequent limited signal; and generating an output signal by subtracting the subsequent difference signal from the subsequent limited signal.
