Abstract:
A means and a method for controlling the transfer characteristics of a device comprised of means for:a means for measuring the deviation of said characteristics from the desired value, a means for encoding certain descriptors of the input to said active device, a means for predistorting the input, prior to the action of said active device, a means for storing a set of correction parameters, according to said descriptors, a means of combining the present value of said deviation with the stored corrective parameters so as to further the corrective effect; wherein the active device is an amplifier; and wherein the instantaneous input power is measured as a complex instantaneous peak or instantaneous envelope and is used to describe the signal the device is to handle wherein the output of deviation measuring device includes measures of amplitude deviation and phase deviation and wherein the said means is comprised of a frequency measuring device delay line discriminator.
