FAQs on Questions: Classification of signals - 1 Video Lecture - Signals and Systems - Electronics and Communication Engineering (ECE)
| 1. What are the main types of signals in electronics and communication engineering? |  |
Ans. The main types of signals are continuous-time signals and discrete-time signals. Continuous-time signals are defined for all values of time, while discrete-time signals are defined only at discrete intervals. Additionally, signals can be classified as analog or digital, where analog signals vary continuously and digital signals have discrete values.
| 2. How can we classify signals based on their periodicity? | |
Ans. Signals can be classified as periodic or aperiodic based on their periodicity. A periodic signal repeats its pattern over a specific interval of time, whereas an aperiodic signal does not have a repeating pattern. Examples of periodic signals include sine and square waves, while aperiodic signals include noise and transient signals.
| 3. What is the difference between analog and digital signals? | |
Ans. Analog signals are continuous in nature and can take any value within a given range, representing physical quantities such as temperature or sound. In contrast, digital signals are discrete and consist of binary values (0s and 1s), making them suitable for digital processing and transmission.
| 4. What are deterministic and random signals in signal classification? | |
Ans. Deterministic signals are predictable and can be described mathematically, allowing their future values to be determined precisely. Examples include sinusoidal waves and step functions. Random signals, on the other hand, cannot be predicted accurately, as they involve inherent uncertainty, such as noise in communication systems.
| 5. How are signals classified based on their energy and power? | |
Ans. Signals can be classified as energy signals or power signals based on their energy and power characteristics. Energy signals have finite energy over time and zero average power, while power signals have finite power and are typically periodic, having infinite energy over time. Examples include a pulse signal (energy signal) and a continuous sine wave (power signal).
