Abstract

According to a prior patent application, the digital user data signal is transmitted in CMI code and, when the code is generated, a binary signal content of the auxiliary signal is allocated to one of the element combinations excluded according to the CMI code rule. Since only the start of a one bit or zero bit of the auxiliary signal is marked, pulses which severely impede the generation of a clock signal occur at the receiving end at comparatively large intervals only. According to a parallel application, a clock pulse pattern is therefore transmitted with sporadic data pulses. The described receiver is able to generate a new clock signal from the clock pulse pattern without the jointly transmitted data pulses being able to cause phase interference. The entire arrangement can be set up fully integrated in CMOS technology. <IMAGE>
