Question:
The spectral density of White noise is
The spectral density of White noise is
Show Hint
White noise = flat (uniform) spectral density.
Updated On: Jul 2, 2026
- Exponential
- Uniform
- Random
- Gaussian
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
White noise has constant power spectral density.
Step 1: Definition White noise contains equal power at all frequencies.
Step 2: Spectral density It does not vary with frequency.
Step 3: Graph Flat spectrum across frequency range.
Step 4: Interpretation Flat spectrum = uniform distribution.
Step 5: Conclusion \[ \boxed{\text{Uniform}} \]
Final Answer: \[ \boxed{(B)} \]
