Dear friends,
I have a question regards to ''tfestimate'' command in MATLAB. I have calculated the transfer function between input and output signals of a system through this command.
TRF=tfestimate(input,output,[],[],2048,1/Ts);
Ts= 0.4
now, this transfer function should be used for another input signal for calculating the output. So, could you please tell me how can I do this ?
Regards Amir

You need a parametric transfer function (that delivers numerator/denominator polynomials) estimator.
