Abstract

The principle of time division multiplexing was known before World War II [Kahn, 76]. But time division multiplexing was not very important, as it was quite complicated to implement this method in analog technique. But since digital memories have become cheaper, more TDM-systems have been introduced. Our system, called Erlangen Voice Scrambling (EVS-) system [Beth, Hess, Wirl, 82] was built for testing and demonstration.
