Chirp sine
WebMar 14, 2013 · The chirp signal shows different frequencies at different times but FFT looks the whole signal (all times) and to achieve that I imagine it generates higher harmonics. There is a reason the matlab example plots a spectrogram and doesn't take an FFT and that is because the FFT of the chirp isn't really a generally useful thing to do.

WebApr 12, 2024 · In this paper, we have proposed an asymmetric image encryption algorithm in the Chirp-Z domain using chaotic Tinkerbell map, DNA coding with biological mutation and phase truncation and phase reservation (PTFT) operation. Most of the DNA based encryption schemes involve XOR operator. The proposed asymmetric scheme uses … WebIn frequency response estimation, a sinestream signal consists of sine waves of varying frequencies applied one after another. Each frequency excites the system for a period of time. You can use a sinestream input signal for estimation at the command line, in Model Linearizer, or with the Frequency Response Estimator block.
