METHOD FOR THE DIGITAL AND / OR ANALOG CODING OF INFORMATION FROM ONE, TWO OR SEVERAL CHANNELS AND / OR REDUCING FREQUENCY OR BANDWIDTH AND / OR INCREASING THE TRANSMISSION SECURITY.

摘要

In this respect, a frequency or time-division multiplexing of channels is already known. This, however, requires substantial expense and a large bandwidth. In the invention, the code elements disposed in series are arranged individually in parallel and are all combined to form a code word. To achieve transmission security, the information is converted into PDM pulses and these pulses are re-coded into the period lengths of half-periods or period lengths which are then transmitted in an uninterrupted sequence of positive and negative half-periods.
