網頁2024年5月29日 · Two things to consider: since your input signal is real (as it not complex), the spectrum is conjugate symmetric. So typically you would only plot the first half from 0Hz to 500Hz. If you want to plot the whole thing, it's better to circulate it and plot it from -500Hz to +500Hz. In most cases you would also use a logarithmic scale (in dB) for ...

網頁1990年8月1日 · Chirp signals have evolved primarily from radar/sonar signal processing applications specifically attempting to estimate the location of a target in surveillance/tracking volume. The chirp, which is essentially a sinusoidal signal whose phase changes instantaneously at each time sample, has an interesting property in that its correlation … 網頁2024年12月12日 · Take the chirp signal x ( t) = e j π α t 2 = e j ϕ ( t) Where α is the chirp rate of the signal. You can see that the function describing the phase, ϕ ( t), is in the form of a quadratic equation. So you can plot ϕ ( t) = π α t 2 and see the quadratic nature of the phase at any point in time.
