Abstract
A system for superimposing data in which data are represented by a constituted analog signal. The analog signal periodically has two presettable levels (high, low), with the data being represented with the time duration of the analog signal. The presettable levels (high, low) of the analog signal can be realized in this context by two different current or voltage values. Other data are present in the form of a constituted digital signal which represents the data in the form of a digital data word. In order to constitute a superimposed signal, a digital signal is superimposed on the analog signal.
