| Abstract: | A method is proposed to suppress nonlinear distortions arising in the acoustooptic analysis of the spectrum of radio signals. The method is based on the polynomial nonlinear correction of an electric signal before it comes to a piezoelectric transducer. The necessary form of the correction is determined in a wide range of parameters of the acoustooptic interaction. The results of numerical simulation are presented. |
