Abstract:
An adaptive apparatus for compensating a linear distorting action to an information signal within a non-ideal transmission system, the system including signal provision means for providing an information signal, and also including output means, the linear distorting action of the system including shifting of at least one aspect of the signal away from its intended value, said apparatus comprising:compensator means, located along a signal stream of the information signal from the signal provision means to the output means, for pre-equalizing the information signal;sampler means for coupling off a sample signal from the output means;determination means, connected to receive the sample signal and the information signal outside of the signal stream from the signal provision means to the output means, for determining an amount of pre-equalization required from said compensator means to compensate the linear distorting action of the system; andmeans for modifying the pre-equalization caused by said compensator means in response to the determination by said determination means.
