I don't see any calls to subplot(). Why not? It tells you to use it. I don't see delay introduced in b, where almost half of it is zero. Why are you not doing the rest of the problem?

And a hint: they want you to use the subplot(), plot(), filter() and filter2() functions. See the documentation on those for example code. And there is also an immse() function to computer mean squared error.
