Let's say I simulate a simple filter in simulink and I want to see the transfer function graph (bode plot) of it. What do I do to get Vout/ Vin? I tried using the "PS Divide" Block and divide the output voltage and the input voltage, but that didn't work. Could anyone help me out here? This is what I tried: http://i1226.photobucket.com/albums/ee410/jean28x/bode1.jpg This is the graph I got: http://i1226.photobucket.com/albums/ee410/jean28x/bode2.jpg Thank you all very much.
