The Measurements of the Satellite Digital Audio Distribution Network

There are two main conditions that the perceptual analysis systems must satisfy. First one is the use of a test signal which has the properties of the ral-world signal, and the other one is the use of some kind of estimation of the temporal behaviour of human hearing at the end of the system.
To satisfy first term we have used our own stimulus - combined test signal, that has statistics similar to real signals. The second thing is proposed measurement method that use mapping from objective to subjective domain. After Hz-bark transformation and appropriate frequency weighting it is possible to calculate overall excitation to excitation in stimulus.
