1.	White noise with power density No/2 = 6 microW/Hz is applied to an ideal filter of gain 1 and bandwidth W rad/s. If the output’s average noise power is 15 watts, the bandwidth W is(a) 2.5 x 10 ^ (-6)(b) 2.5p x 10^(-6)(c) 5 x 10^(-6)(d) p5 x 10^(-6)I have been asked this question in quiz.I want to ask this question from Random Process in chapter EDC Overview of Electronic Devices & Circuits
Answer» RIGHT choice is (b) 2.5p x 10^(-6) The best I can explain: Pyy = 1/2p Integral(?xx(W) \|H(w)\|^2 dw ) from PLUS infinity to minus infinity. Hence solve for W.
