DHANALAKSHMI COLLEGE OF ENGINEERING DEPARTMENT OF ELECTRICAL AND ELECTRONICS ENGINEERING EE6403- DISCRETE TIME SYSTEMS AND SIGNAL PROCESSING UNIT I INTRODUCTION – PART A Classification of systems : Continuous and Discrete What are the various classifications of discrete time system? Linear and Causal System Define Causal System − Dynamic and time variant systems What is meant by linear time invariant system? (A-08) Differentiate static system from dynamic system. Classification of signals : Continuous and Discrete Define Even Signal and Odd Signal (A-11) − What is meant by deterministic signal? Define Random Signal − What are the different types of operations performed on discrete time signals? Sampling Techniques Define Sampling (M- 09) − State sampling theorem. (M-10) Quantization, Quantization Nyquist rate, aliasing effect Define Rate (M- 12) −Nyquist What is meant by aliasing effect? (A-11) What is meant by quantization error?
