Abstract
An arrangement for monitoring an alternating signal with respect to its state as mark-to-space ratio or direct-current component, in which the alternating signal is modified so that its mark-to-space ratio or direct-current component can be detected by simple comparison with reference signals. Various information is then transmitted over a line, and the operation of the stage that generates the alternating signal can also be monitored.
