Figure 9From: Analysis, Synthesis, and Classification of Nonlinear Systems Using Synchronized Swept-Sine Method for Audio EffectsComparison between the real-world output of pedal 2 (blue-dashed) and the GPH model-based output (red-solid) in time (a) and frequency (b) domains, for a sine wave excitation with Hz and V. The GPH model is estimated using a swept sine signal with amplitude V. For the sake of clarity, the output of the real-world device in the frequency domain is shifted to the right.Back to article page
