Consider the following noise model for a simple resistive voltage divider: Vi=+0V - www . Vo m2 R₂ where R1 = 6.1 kOhms and R2 = 3.9 kOhms. You measure the output voltage with a 50kHz scope at 300K. Calculate the RMS noise voltage in the output. Give your answer in microvolts to 2 decimal places. [Hint: Consider the effects of both Johnson noise and shot noise independently, that is, ignore the effects of one when calculating the other. Assume the 50kHz bandwidth of the scope has a hard "brick-wall" frequency dependence at the cut-off frequency.]
