**Preamble**

Discrete-Time Signal processing is concerned with the representation, transformation, and manipulation of signals and the information they contain. It is an area of science and engineering that has developed rapidly over the past few decades. The novel algorithms by Cooley and Tukey (1965) for efficient computation of Fourier transform provided a new point of view towards discrete-time signal processing. This course aims at the analysis and design of signal processing systems and computational techniques.
**Prerequisites: Signals & Systems **

**Course Objectives **

Signal Processing has developed rapidly over the past few decades and has numerous applications in the field of Audio and Speech Processing, Radar, Sonar, Robotics, Big data, Biomedical, and many more. In this course, we begin with the review of Signals and Systems including the summary of analysis and synthesis equation for Fourier Transforms tools and z-transform. An in-depth computation of DFT and FFT algorithms in spectral analysis and filtering applications is presented. This course develops different methods of filter design in both IIR and FIR and the corresponding structures. The effect of quantization is analyzed in digital filters using finite precision arithmetic. This includes the effects on the filter frequency response characteristics resulting from quantization and round-off noise effects inherent in the digital implementation of discrete-time systems.

##### COURSE OBJECTIVES

Blockchain is an emerging technology platform for developing decentralized applications and data storage, over and beyond its role as the technology underlying the cryptocurrencies. The basic tenet of this platform is that it allows
to create a distributed and replicated ledger of events, transactions, and data generated through various IT processes with strong cryptographic guarantees of tamper resistance, immutability, and verifiability. The global blockchain
market size is expected to grow from USD 3.0 billion in 2020 to USD 39.7 billion by 2025. The objective of this course is to provide conceptual understanding of how block chain technology can be used to innovate and improve business
processes. The course covers the technological underpinning of blockchain operations in both theoretical and practical implementation of solutions using blockchain technology.
