Patent ID: 6853685

Claim:
A transmission channel for transmitting digital signals with a first digital-signal port for a first digital signal to be transmitted, and with a second digital-signal port for a transmitted second digital signal, said transmission channel comprising: an isolating path with a predeterminable isolation capability; a first conversion stage having a coupling-signal port for a first coupling signal transmissible across the isolating path; and a second conversion stage having a coupling-signal port for a second coupling signal transmissible across the isolating path, the isolating path being provided between a coil of the first conversion stage and a coil of the second conversion stage, and the second conversion stage converting the second coupling signal to the second digital signal by means of a monostable multivibrator having a set input coupled to the second coupling signal port and having an output coupled to the second digital-signal port, said second digital signal representing said first digital signal.
