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
