Abstract :
Many actual design engineers involved with analog television broadcast systems are now faced with designing, operating, and maintaining of digital television systems. The essential purpose of this paper is to make an innovative study to analyze the transition from analog to digital television broadcasting which turns out more efficient the job of the designers. Their activities must to take into account all imposed international norms and at the same time to ensure a high quality of the digital transmitted signal. An accurate study in the performance of the amplifiers has extreme importance for applications, which have a great interest to reduce the distortions present in the transmission of the digital signals. The numerical approach described here uses an efficient algorithm which will help us in the modeling of a digital pre-distortion module, which has the main function of to minimize the distortions that appears an intrinsic way in the transmitted signal.
