Homework Statement
I have a bode plot with a positive phase.
Homework Equations
this is a MATLAB code for the thing
Code:
% bode phase plot
w = logspace(1, 4, 100);
G = 100*(1+0.017i*w)./(1i.*w.*(1+0.05i.*w).*(1+0.0025i.*w).*(1+0.001i.*w));
fi = atand(imag(G)./real(G));
semilogx(w, fi); % x-axis: log(omega*j), y-axis: phase in degrees
The Attempt at a Solution
Nothing to solve, there's just one thing I don't get: if phase means "relation between input and output signal", how can output signal come before the input?
