AB  - This paper studies the impact of applying a fade-in and fade-out to smooth the start and end of swept-sine signals used for characterizing nonlinear systems. The absence of fade-in and fade-out can lead to significant overestimation of higher harmonics, affecting the accuracy of nonlinear analysis. Through empirical validation, we demonstrate that applying fade-in and fade-out to the swept-sine signal effectively reduces the overestimation of higher harmonics, thus improving measurement accuracy. This improvement is crucial for applications such as amplifier testing and high-fidelity loudspeaker analysis, where precise measurement of harmonic distortion is essential.
