Claim:
1. A method for measuring the transmission characteristics of a first transmission path between a first transmitter and a receiver, the method comprising: the first transmitter sending a first signal into the first transmission path, the first signal being detected by the receiver after it passes through the first transmission path; a second transmitter sending a second signal into a second transmission path that can be predetermined; and the second signal is received in the receiver after it passes through the second transmission path and is superimposed with the first signal; a transmission signal is at least intermittently distributed between the first transmitter and the second transmitter in a controlled manner; a receiver signal received by the receiver comprises first and second signal components to be assigned to the first and second transmitters, respectively, wherein the first signal component averaged over a predefined time period is exactly as large as the second signal component averaged over said time period; and the deviation of the first signal component averaged over said predefined time period from the second signal component averaged over said predefined time period is at least intermittently used as a control signal for the distribution of the transmission signal between the first transmitter and the second transmitter, whereby the first transmitter and/or the second transmitter can be digitally activated.
