FAQs on Introduction to Pulse Modulation Video Lecture - Communication System - Electronics and Communication Engineering (ECE)

1. What is pulse modulation in electronics and communication engineering?
Ans. Pulse modulation is a method used to encode analog information in digital form by varying the width, position, or amplitude of pulses in a signal.
2. What are the different types of pulse modulation techniques used in communication systems?
Ans. Some common types of pulse modulation techniques include Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), and Pulse Position Modulation (PPM).
3. How does Pulse Amplitude Modulation (PAM) work in communication systems?
Ans. In Pulse Amplitude Modulation (PAM), the amplitude of the pulse is varied according to the analog signal being transmitted, thus encoding the information.
4. What are the advantages of using pulse modulation in communication systems?
Ans. Pulse modulation techniques offer advantages such as improved signal-to-noise ratio, efficient use of bandwidth, and ease of digital processing.
5. How is Pulse Width Modulation (PWM) different from Pulse Position Modulation (PPM)?
Ans. In Pulse Width Modulation (PWM), the width of the pulses is varied to encode information, while in Pulse Position Modulation (PPM), the position of the pulses is varied.
