Digital signal exercise (Manolakis)

[MaxR2018]

Homework Statement

Determine the impulse response of the equivalent system.

Relevant Equations

How to start this exercise?

Hello people, I hope someone can help me with this exercise. This exercise is taken from the book "Applied Digital Signal Processing: Theory and Practice" by manolakis and Ingle. I don't understand what is being asked. The only thing I understand is that I have to use MATLAB necessarily. Someone has the solution of the book or knows how to do it? or at least a clue or suggestion.

Thank you for your time people.

Hello Max,
You've been around for a year but never been 'd ?

Nevertheless, you should know by now that the PF guidelines require some effort on your part before we are allowed to assist... (previously called the 'attempt at solution')

And that 'dunno' ('How to start this exercise? ' is NOT a relevant equation!) isn't good enough !

You could start with a few explanations: what does MATLAB return from e.g.

ones(1,5)

?
And what does it return from

conv([1,-1, -1, -1, 1], x)

when x is e.g. [1,2,2,1] ?
These things you can try out yourself.
You could also type out the problem statement, so helpers can comment without having to retype ...

I grant you the word 'response' occurs awfully often in the book, but you should still be able to pick an appropriate example and use that by way of 'relevant equation'(By the way, I'm not a Matlab expert, nor a DSP expert and until ten minutes ago I'd never seen the book -- so I'm at the same point as you are with this exercise)

Now it's your turn...

I don't understand what is being asked.

What is being asked is what is the one-step equivalent of those three steps. What is the $h$ that would be equivalent to those three.

This is not a Matlab question, it's a question about convolution and impulse responses and linear systems, although Matlab knowledge would be helpful in relating those calls to convolutions in your textbook.
