The supplied data contain the experimentally measured impulse response (IR) of three unknown filters

The supplied data contain the experimentally measured impulse response (IR) of three unknown filters that are identified as unknown_filter_1_IR, unknown_filter_2_IR, and unknown_filter_3_IR. Modify the supplied program to perform Fourier transform on these IRs and identify what type of filter it is and what is/are its cutoff frequency (or frequencies in case of bandpass and bandstop filters). Paste the results below as asked for. Zoom in on the FR of each filter to concentrate on and display DC to the 250 Hz region and paste the pictures for this frequency region only.
