Abstract
A transmission system ( ) broadcasts an information signal. Within the system ( ), several components (e.g., ) cause distortion to the information signal as the signal is processed and proceeds toward a broadcast antenna. Specifically, the group of distortion causing components ( ) is identified as a first group, and is arranged in a sequence along a signal path ( ) toward the antenna. The first group of components ( ) performs various functions, including amplification, but each subjects the information signal to distortion shifts away from intended values. A second group of components (e.g., ) modifies the information signal to compensate for the distortion shifts imposed by the first group of components ( ). The second group of components ( ) is located upstream of the first group of components ( ). The second group of components ( ) is arranged in a sequence to modify the information signal to compensate for the distortions in an order inverse to the occurrence of the distortions. Specifically, compensation for linear and non-linear distortions occurs in an order that is inverse to the occurrence of the linear and non-linear distortions.
