WebOct 6, 2024 · The MATLAB built-in function chirp generates a swept-frequency cosine signal, where the frequency sweep is based on the type of sweep ordered in the chirp command (linear, quadratic, logarithmic, etc). The output is essentially a passband modulated signal. What if I want to see the chirp in baseband? 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. matlab chirp Share
