WebThe ripples in the amplitude spectrum of a linear spectrum is undesirable. I desire to obtain a flat spectrum response. Hence, how can I remove these ripples? Also, which factors (like time bandwidth product, chirp rate) are affecting the ripples, and how? I designed a chirp with a frequency from 10 to 90 Hz in MATLAB.

WebJun 27, 2016 · Using the chirp intraoperatively, you can get a response more quickly, and provide feedback to the surgeon more quickly. Roland Muhler has done work in this area (e.g., Muhler et al., 20014). He has shown that you can record ASSRs in a matter of 10 seconds - not the entire ASSR, but you can detect a response for one frequency in little … A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications … See more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness).

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.
