The noise X in a eertain electronic system is a Gaussian random variable with mean p= and variance oz. The normalized instantaneous power of the noise is given by Y=Xzf o2, where the parameter oz can be interpreted as the average noise power. Compute the pdf of the noise power. (151;!) 24) Gaussian surfaces A and Benclose the same positive charge . Q. The area of Gaussian surface A is three times larger than that of Gaussian surface B. The flus of electric field through Gaussian surface A is A) three times larger than the flux of electric field through Gaussian surface B. B) equal to the flux of electric field through Gaussian surface B. C) nine times larger than the flux of electric field through Gaussian surface B. D) unrelated to the flux of electric field through Gaussian surface B. E) three times smaller than the flux of electric field through Gaussian surface B.E) toward fifty 9) Gaussian surfaces A and B enclose the same positive charge +Q. The area of Gaussian surface A is three times larger than that of Gaussian surface B. The flux of electric field through Gaussian surface A is A) nine times larger than the flux of electric field through Gaussian surface B. B) unrelated to the flux of electric field through Gaussian surface B. C) equal to the flux of electric field through Gaussian surface B. D) three times smaller than the flux of electric field through Gaussian surface B. 10) If the electric field is in the positive x direction and has a magnitude given by E = Cx', where C is a constant, then the electric potential is given by V= A) 2Cx B) -2Cx C ) CP3 /3 D) -Cx/3 E) -30
