(b) The Matlab routinesampdatahas been provided in the course website. Use thesequence generated by this routine as input for the filter simulations in this prob-lem. (c) Write a Matlab routine to simulate the second order section implementation ofH(z) using second order IIR lattice sections and your function from part a. Sincethe order of the filter is 6, your implementation should have 3 second order sectionsand you should call your routine 3 times to implement the cascaded filter.
