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