Chapter 1 Introduction

Welcome to the course. This will be an interactive course, where students will participate in the learnings while writing code to reinforce concepts.

1.1 Prerequisites

The prerequisite for this course is Signals and Systems (EE 210) or equivalent. If you have doubts about this, consult the instructor. This course cannot be taken by B.Tech. and Dual Degree students.

1.2 Topics

We will cover the following topics:

  • Review of signals, systems, Fourier transform and Fourier series
  • Sampling theorem
  • Discrete-time signals and systems
  • Discrete-time Fourier transform and \(z\)-transform
  • Discrete Fourier transform and FFT
  • Design of digital filters
  • Applications: image compression, OFDM, and more…

1.3 Textbook

The textbook used will be “Discrete-Time Signal Processing” (3rd edition) by Oppenheim and Schafer (Oppenheim, Buck, and Schafer 2001). The textbook should be considered required, since there will be several reading assignments from the book. “Foundations of Signal Processing” (Vetterli, Kovačević, and Goyal 2014) can be considered for supplementary reading.

1.4 Teaching Assistants

To be announced

1.5 Evaluation

To be finalized. Fortnightly homeworks will be issued, and these would be part of the evaluation.
