Transfer Function in MATLAB

  1. Nov 17, 2008 #1
    Hi

    I have a transfer function< I want to draw a bode diagram in MATLAB, the transfer function is for a simple HPF when I use MATLAB to find the magnitude and phase shift it giving a wrong diagram, the transfer function is:

    =RCs / (RCs + 1)
    I want to know how shoud I have to manipulate this function in MATLAB to find the correct answer?
    Capacitance = 220 nF
    R = 10 kilo ohm
    Thanks

    s=tf('s');
    RC=220e-12*1e4;
    G=RC*s/(RC*s+1);
    bode(G)
