Abstract :
The digital innovation of transmitters is one of key technologies for digital SW & MW broadcasting. Aiming at the transmitters using EER (Envelop Elimination and Restoration) technology, the paper discussed the key problems in digital innovation practice, and the conclusion of the effects on digital broadcasting signal quality of the problems are also provided based on specific simulations. A set of practical parameters based on a given engineering conditions are described in the end and the related simulation results of the output digital broadcasting signal quality is provided.
