Ideal white noise has approximately what power spectral density over the frequency range where it is considered white?

  • AConstant
  • BProportional to 1/f
  • CZero at every frequency
  • DA single spectral line
Report an error
Correct Answer: A. Constant
Explanation: White noise is modeled as having approximately flat power spectral density over the frequency band of interest.
Reference: Standard analog electronics: white noise
