Pulse Modulation Techniques | PAM vs PWM vs PPM | Digital Communications| Btech

Описание: Welcome to the second lecture of Digital Communications Unit-1!
In this video, we clearly explain PAM, PWM, and PPM — the three major Pulse Modulation Techniques used in analog and digital communication.

This lecture is perfect for:
✔ B.Tech
✔ ECE / EEE / CSE AIML
✔ Exam preparation, assignments, and viva

🎯 Topics Covered in This Video:
• What is Pulse Modulation?
• PAM (Pulse Amplitude Modulation)
– Natural PAM
– Flat-Top PAM
• PWM (Pulse Width Modulation)
• PPM (Pulse Position Modulation)
• Waveform diagrams
• Applications of PAM, PWM, PPM
• Comparison Table
• Most important points for 10-mark questions

This explanation follows the official Andhra University Digital Communications syllabus (EC3102) and is 100% exam-oriented.
