JNTUK B.TECH ECE BRANCH - DIGITAL SIGNAL PROCESSING IMPORTANT QUESTIONS
UNIT-I:
- Classification of Discrete time systems & Review of Z-transforms
- Discrete time signals & sequences
- Relation Between Z-transforms & DFT
- Prepare More Problems (Convolution, Z-transforms, Transfer functions, DTS)
- Causality and Stability
- FDR of discrete time signals and systems
- Learn about LTI systems (Stability…)
UNIT-II:
- Properties of DFS & DFT
- FFT vs Inverse FFT (imp)
- Prepare More Problems on DFT, IDFT & FFT
- 8-point DFT & DIT
(Students, these are the most important topics, and there are very high chances that they will ask more problems, so try to prepare all the problems)
UNIT-III:
- Design of IIR Digital Filters from Analog Filters (most imp)
- Butterworth & Chebyshev (most imp question)
- Impulse Invariant Method & Bilinear Transformations
- Problems on (Impulse Invariant Method, Butterworth Filter, Bilinear Transform…)
(if you have more time then prepare "Transposed forms")
UNIT-IV:
- Comparison of IIR & FIR Filters (imp)
- Problems on “Parallel Realization, Lattice Filter, System Function…”
- Design of FIR Digital Filters
- FIR Systems, Lattice Structures (imp)
UNIT-V:
- Multiple Access Memory, VLIW Architecture, Pipelining (imp)
- Explain the Architecture of TMS320C5X & Parallel Logic Unit
- Bus Structure & On-chip Peripherals of TMS320C5X
- Special Addressing Modes & On-Chip Peripherals in DSP Processors (imp)
- Multiplier and Multiplier Accumulator
- Some Flags in the Status Registers & Memory Mapped Registers
