This video presents our Signal Networks and Systems (SNS) Mini Project on DTMF (Dual Tone Multi-Frequency) Tone Generation.
DTMF technology is used in telecommunication systems to transmit signals through audio tones, representing digits and symbols on a keypad.

In this project, we demonstrate the process of generating DTMF tones, explain how two frequencies (low and high) combine to represent each key press, and explore its practical use in telephone systems and digital communication.

🎓 Project Highlights:

Introduction to DTMF Technology

Theory Behind Dual Tone Generation

Implementation Using Signal Networks and Systems Concepts

Simulation / Practical Demonstration

Applications in Modern Communication


📅 Year: 2025
🎓 Department: Electronics & Communication Engineering
