* Lecture 4: Discrete time signals and systems

Discrete time signals and Systems

Course Outline:

• Type of systems

• Linear System

• Time Invariant System

• Memory and memoryless systems

• Causal System

• Discrete Time Signal

• Linearity

• Time Invariant & Variant

• Causality

Note: You should be able to differentiate between different type of systems and signals and perform mathematical analysis to justify each condition.
