Hi there, I'm having a hard time trying to plot a Bode Diagram here in MatLab. The transfer function not only has an exponential function in it, but also has 3 unknowns to which I am not supposed to assign value, and on top of that it is a complex number. Let me write it down to you: H(s) = A * exp(-s*B + j*C) A and B are just two "unimportant" unknowns, but "C" is the function's Phase. I don't know if it is possible to plot the diagrams without assigning values to A, B and C, but I'm asking you guys here anyway. Thank you very much. Regards, Ramon.
