Query: Theory, NOT Application

This is a book focus on the theory.It concentrate on how to derive equations,rather than how to solve problems.Therefore, it contains very few examples and no MATLAB code.Also, this book assumes that the readers are already familiar with z-Transform.If this is your first exposure to Z-transform, you will have difficulty from Chapter 1.Also, aware that every exercise problems have VERY LONG list of subproblems.Most problems easily have sub-problems from (a) (b) (c) ... to (k).Some of them goes to (a) (b) (c) ... to (p) !!It takes A LOT of time to solve one problem completely.If you make one mistake in the middle, you are screwed.I wouldn't recommend this book as a learning tool.Instead, I would suggest"Digital control of Dynamic System" by Franklin or"Discrete Time Control System" by Ogata.Both of them were far easier to read and focus on problem solving.
