The … WebSep 16, 2024 · The chirp function I have written so far is-. function c = chirp (signal) u = signal; ut = gradient (signal); utc = conj (ut); numval = imag (sum (u.^2 .* utc.^2)); denval = sum (abs (u).^4); c = numval/denval; end. However, this is giving incorrect answers. Any help pointing me in the right direction would be much appreciated.

WebA chirp is a signal of the form r(t) = Asin(2no(t)) where A is the amplitude and the function o(t) is the phase of the chirp. If the phase has the form $(t) = fof1 ti - to (fi - fo In + 0, f1 fi-fo (t - to), then the signal is called a hyperbolic chirp. WebApr 9, 2024 · 1. @mi1000 I think they need all the if statements.
