Performance evaluations and measurement principles of hybrid information carriers, that is, carriers for partly analog and partly digital source infomation, are established. Simulation requirements, which are independent from a particular hybrid configuration or system capacity, for the analog and digital sources are presented. In order to perform the analysis of multilevel digital streams, a simple formula for the power spectrum density of the random -level Gray-coded stream is derived. With normalization of the formula, the same power density spectrum for any number of levels is achieved. The required length of the pseudorandom sequence as a function of the transmission characteristics and hybrid environment is established. The measurement difficulties, when the noise source is not Gaussian, are discussed. |
