Filtering Long Sequences Using DFT | Overlap Add & Save Methods | DSP by Dr.B. Ravi Chandra Sir

📚 In this lecture, **Ravi Chandra Sir** from **G Pullaiah Engineering College** explains **DFT-based filtering techniques** used for **long data sequences** in Digital Signal Processing (DSP).

The lecture focuses on:
✅ **Filtering Long Sequences using DFT**
✅ **Overlap-Add Method**
✅ **Overlap-Save Method**
✅ **Related Problems & Numerical Examples**

These methods are crucial for efficiently filtering signals that are too long for direct convolution, especially in **real-time systems** and **embedded DSP applications**.

🎯 **Topics Covered:**
- Block convolution using DFT
- Step-by-step explanation of Overlap-Add and Overlap-Save
- Comparison with linear convolution
- Problem-solving techniques for exams
- Applications in audio, communication, and biomedical signals

👨‍🏫 **Faculty:** Ravi Chandra Sir
🏫 **Institution:** G Pullaiah Engineering College
🎯 **Best For:**
- B.Tech (ECE, EEE, CSE)
- GATE, ESE, PSU Aspirants
- JNTU/VTU/AKTU DSP syllabus
- Practicing engineers and DSP learners
