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.
