ABSTRACT:
A system for and method of compensating for performance differences in a set of information channels is disclosed. The system and method model each channel as linear and characterizes the channel by an offset and a gain. The system includes memory for storing the offsets and gains associated with the N channels. The system further includes means for mathematically adjusting the output of each information channel by that channel's associated offset and gain. The system further includes filters for reducing the effect of random noise on the measurements of the offsets and gains by generating signals representative of time weighted averages of the offsets and gains.
