Chirp python

WebSep 2, 2024 · Most signal processing texts have mostly math formulas with continuous variables, so it's easy to think writing cos (2 * pi * f * t) in Python or MATLAB would mean that your angular phase is 2 π f t and therefore frequency is the variable f, regardless of what the code variables t and f hold. WebA numpy array containing the signal evaluated at t with the requested time-varying frequency. More precisely, the function returns cos (phase + (pi/180)*phi), where phase is the integral (from 0 to t) of 2 * pi * f (t); f (t) is defined above. See also chirp Notes New in …
