Hi
i have a question regading impulse response. I have poles and zeros and i can easily evaluate transfer function using tf command.
Now i want to get impuse response in terms of time domain variables. I want to evaluate impuse response from the given poles and zeros. What command i have to use?
 

Hi,
You have to create a state space system for getting impulse response in time domain.
For example
Sys1 was defined in terms of the transfer function using poles and zeros .Create a new state-space(ss) system, Sys2, that is equivalent to the transfer function system Sys1.
For creating ss - system u can use the following command in matlab
'impulse(ss(tf(b,a)))' '
 

Hi
There is one important notice. MATLAB version 7.10.0 is having the above mentioned command but MATLAB version 7.7.0 is not having this command so kindly specify your MATLAB version
 

thank you for your replies. i am using MATLAB 7.8.0
