ANALYSIS OF METHODS TO IMPROVE ENERGY EFFICIENCY OF DIGITAL BROADCASTING

Abstract

The main characteristics of the signals of digital broadcasting standards are
considered. It is shown that for amplification of digital signals it is necessary to use
high-linear amplifiers, which have a significant drawback - low efficiency in the
mode of average power. Based on the analysis of the properties of methods for
improving the energy efficiency of linear power amplifiers, recommendations have
been formulated for using them for signals of various broadcasting standards.
