35.
Noise with uniform power spectral density of N0ω/Hz is passed through a filter H(ω) = 2 exp (-J ω ty) followed by an ideal low pass filter of bandwidth B Hz. The output noise power in watts is
Answer: Option
Explanation:
Output spectral power density
= | H(ω) | x I/P spectral power density
= 2 x 2N0 
4N0
Output power = 4 N0B.
