A transmission system (14) broadcasts an information signal. Within the syst em (14), several components (e.g., 20-24) cause distortion to the information signal as the signal is processed and proceeds toward a broadcast antenna. T he group of distortion causing components (20-24) is identified as a first grou p, and is arranged in a sequence along a signal path (12) toward the antenna. T he first group of components (20-24) 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., 28-32) modifi es the information signal to compensate for the distortion shifts imposed by th e first group of components (20-24). The second group of components (28-32) is located upstream of the first group of components (20-24). The second group of components (28-32) is arranged in a sequence to modify the information signa l to compensate for the distortions in an order inverse to the occurrence of t he distortions.
