Abstract
A transmission level indicator circuit arrangement is provided which generates an output signal when the amplitude of incoming data signals exceeds a predetermined threshold. The circuit arrangement includes an integrator which receives a first voltage obtained from the data signals superimposed upon a second voltage of opposite polarity which is proportional to the first voltage in relation to the signal noise ratio for interpretation of the data signals. The integrator output forms the transmission level indicator signal.
