For convenience, the shorter names shown below may also be used. linear, lin, li: f (t) = f0 + (f1 - f0) * t / t1 quadratic, quad, q: The graph of the frequency f (t) is a parabola through (0, f0) and (t1, f1). 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. deck world seneca sc https://kathsbooks.com
