<p>A correlation transmission encoder that generates a signal sent through a transmission path determined by data sequences which have already been transmitted and by transmission data, by adding a frame synchronous pattern of a predetermined length for every fixed frame period in a similar way of the partial response class 4 encoding signal, and a correlation transmission code system using the encoder. The feature resides in the provision of means (7, 50, 71, 72, 73) that reset and preset the resistors (41, 42, 43) commonly used by a transmission system constituting the above encoder and by a precoder for each frame period, or of means (6, 8a, 8b, 10, 179) that insert internal data to be added to the transmitted data in the transmission system and in the precoder just before the frame synchronous pattern.</p> |
