I have a first order transfer function of the form :
and I know its output form for a step input
I tried impleneting it using transfer function block in simulink with a step input, and didn't get the expected result
But, when implementing it using the LTI block I got the exepected reuslt.
My question is, why the outputs are different, shouldn't they be the same since the trasnfer function can also represent an LTI system?
Thank you

Can you provide more details explaining exactly what you tried. I see identical output from from the LTI block and the Transfer Function block for a0 = 1 and b0 = 2.
