Abstract

A method for increasing the information density on a signal-transmission line. The signal-transmission line extends from a sensor to a control unit. A modulated signal, which includes a digital signal, is transmitted on the signal-transmission line. The digital signal assumes either a high level or a low level. The modulated signal includes an encoded pulse signal, which is superimposed on the digital signal and has both an encoded pulse duration and a variable pulse frequency.
