Signals and Systems Lec-55: Block Diagram Representation for Discrete-time LTI Systems

Signals and Systems Lec-55: Block Diagram Representation for  Discrete-time  LTI Systems
                                In this Lecture, concept of block diagram representation for discrete-time  LTI systems  is discussed using z-transform. i.e different types of realizations like direct form 1 and 2, cascade form and parallel form are explained through the example problems. And i also solved previous GATE questions.
