Circuit arrangement for recovering the clock signal contained in a CMI signal

摘要

A circuit arrangement is described with the aid of which the clock signal contained in a CMI signal can be recovered. In this circuit arrangement, the CMI signal is present at the clock input (26) of a negative edge-triggered flip-flop (28). A saw-tooth generator (36), which starts a new leading edge of its output signal with each edge of the signal emitted by the flip-flop (28), which is fed to its input, is connected to the output of the flip-flop (28). The output of the saw-tooth generator (36) is connected to a bandpass filter (42) whose pass band is tuned to the frequency of the clock signal to be recovered. <IMAGE>
