Course Modules

This specialization consists of four modules. Module 1 covers basic concepts and algorithms, including discrete-time signals and the Fourier transform. Module 2 focuses on digital filtering, design, and adaptive signal processing. Module 3 explores the differences between analog and digital signals, including sampling, interpolation, and multirate signal processing. Module 4 delves into image processing, digital communication systems, and real-time DSP algorithm implementation on microcontrollers.

Digital Signal Processing 1: Basic Concepts and Algorithms

The first module, Digital Signal Processing 1: Basic Concepts and Algorithms, provides a solid foundation in discrete-time signals and their analysis in the frequency domain via the Fourier transform. Learners will gain a deep understanding of the nature of discrete-time signals and their representation as vectors in a vector space.

Digital Signal Processing 2: Filtering

The second module, Digital Signal Processing 2: Filtering, delves into digital filters, their functionality, design, and adaptive signal processing. Learners will explore the practical application of digital filters and gain expertise in manipulating signals using various filter techniques.

Digital Signal Processing 3: Analog vs Digital

Module 3, Digital Signal Processing 3: Analog vs Digital, elucidates the differences between continuous and discrete time, sampling, interpolation, and quantization. Learners will understand the process of converting analog signals into digital format, the working of A/D and D/A converters, and multirate signal processing.

Digital Signal Processing 4: Applications

The final module, Digital Signal Processing 4: Applications, covers the basics of image processing, the working of digital communication systems such as ADSL, and the implementation of real-time DSP algorithms on a microcontroller. Learners will gain practical skills in programming microcontrollers for real-time DSP applications.
