Hi there, I am measuring the output of a mechanical manipulator in response to
band limited gaussian white noise. This then allows me to calculate the transfer
function using - cross-power spectral density of the stimulus and the response
divided by the auto-PSD of the stimulus. I have been able to achieve this in
matlab. Now, I want to nullify the effect of the manipulator using a inverse
filter with 1/transfer function of the manipulator. This will ensure that the
noise that I inject in the manipulator passes faithfully without imposing the
transfer function of vibrator. Please advise how could I achieve this in matlab.
Shall I use invfreqz to get the a and b coefficients and then filter my input
data using this or is there some other way?
