Abstract :
A hybrid digital transmission system of the kind originally proposed by Chang and Freeny [4], [6] is considered. Based on predictions about cable and repeater costs around 1980, an investigation of a certain economic measure of goodness is performed. Specifically, the influence on the system cost of the choice of certain fundamental system parameters like repeater spacing, symbol rate, and number of signal levels is studied.
