Abstract
A transmission system for the transmission of binary data symbols is described in which a so-called 'crankshaft code,' in combination with a receiver having a special filter characteristic, enables a more optimum signal detection, independent of the cable characteristic. The system is used for digital transmission over cables in the local telephone network.
