description: The influence of the type of power amplifier in conditions of limited range on the efficiency of clipping and filtering to reduce the peak factor, and the spectrum band of SEFDM signals is studied. The study is conducted for two types of amplifier, to check the influence of the type of amplifier on the effectiveness of clipping and filtering. As an aspect of evaluating the energy efficiency of systems, the value of energy loss is used. As an argument for evaluating the effect of the signal bandwidth, we use the graph of the dependence of the spectrum width on the value of the displacement of the working point of the amplifier. A model was developed for receiving SEFDM signal transmission using clipping, filtering, and two types of amplifier. Obtained dependence of the energy loss and the bandwidth of the spectrum in certain level the type of amplifier, the level of the threshold of clipping, the bias operating point of the amplifier and filtering in the model. Based on the results of the study, it becomes possible to assess the degree of influence of the type of amplifier on the efficiency of clipping and filtering in the transmission of SEFDM signals, namely on the spectrum bandwidth and energy efficiency.
