I am trying to determine the Filter properties mostly stop band attenuation of a FIR Filter designed by the given coefficients stored in a row vector. To design the filter from the given coefficients, I am trying to use either 'dsp.FIRFilter' or 'dfilt.dffir'. I am not able to use the 'measure' command on the objects obtained.
Is there any other command (other than measure) using which I can extract the value of the stop band attenuation which I have to compare with a given value?
