Abstract
An evaluator for evaluating a digital transmission system is provided which comprises a signal power decrease detector and a system margin evaluator. The signal power decrease detector receives a digital signal which has been transmitted through the transmission medium of a transmission system so as to generate a signal power decrease signal. The system margin evaluator evaluates the system margin of the transmission system in response to the signal power decrease signal. The system margin of the digital transmission system can be evaluated in a simple and convenient manner.
