A DEVICE AND METHOD FOR CONTROLLING THE AMPLITUDE OF SIGNALS

摘要

A device for ensuring that the amplitude of signals fall within a predetermined range, said device comprising input means (34) for receiving a plurality of input signals at substantially the same time, a first path for increasing the amplitude of any of the input signals having an amplitude below a first threshold, a second path for decreasing the amplitude of any of the input signals having an amplitude which exceeds a second threshold and combining the outputs of the first and second paths (78) to provide a plurality of signals having amplitudes between said first and second thresholds.
