FAQs on Classification of Signal Explain Video Lecture - Communication System - Electronics and Communication Engineering (ECE)

1. What is a signal in the context of Electronics and Communication Engineering?
Ans. In Electronics and Communication Engineering, a signal is a function that conveys information about a phenomenon. Signals can be classified based on various characteristics such as amplitude, frequency, and phase.
2. What are the different classifications of signals?
Ans. Signals can be classified as continuous-time signals and discrete-time signals. Continuous-time signals are defined for all values of time, whereas discrete-time signals are defined only at discrete points in time.
3. How are signals classified based on amplitude?
Ans. Signals can be classified as analog signals and digital signals based on amplitude. Analog signals have continuously varying amplitude, while digital signals have discrete amplitude levels.
4. What are periodic and aperiodic signals?
Ans. Periodic signals repeat themselves at regular intervals of time, while aperiodic signals do not exhibit any regular pattern in their occurrence.
5. Can a signal be classified based on its symmetry properties?
Ans. Yes, signals can be classified as even signals, odd signals, or neither based on their symmetry properties. Even signals are symmetric about the y-axis, odd signals are anti-symmetric about the origin, and neither signals exhibit neither symmetry.
