Block Diagrams and Review of Discrete System Representations

6.1    Introduction

Block diagrams are representations of physical systems using blocks. They are among the many representations such as transfer function representation, impulse response representation, difference equation representation, state-space representation, etc. Each of these representations, including the block diagram representation, gives a complete description of the system under consideration. Some of them are better than the others and that depends on the system itself. Individual blocks can be put together to represent the physical system in block diagram form. Individual blocks can be the basic blocks or they can be subsystems. The discussion we will undertake ...
