The non-linear analysis of the samples is performed using sideband peak count (SPC). The SPC technique counts the number of peaks in the FFT plots for given threshold values [10]. In general, a linear material shows fewer peaks compared to a non-linear material. Therefore, SPC values for linear and nonlinear materials should be different.
