Homework 2_1 ECET310 NOISE 1. Assume that a receiver has a first amplifier stage with a 5K input resistance‚ a gain of 300‚ an input audio signal of 20 V‚ and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz‚ find (a) the rms input noise levels (b) the audio output levels (c) the rms output noise levels PN = noise power in watts Tk = 27°C + 273 = 300°K a) Noise level Pn(in) = KT(k)BW = (1.38x10-23)(300°K)(10MHz) = 41.4 x 10^-15 W

1.Which statement is true about broadcast and collision domains? Adding a router to a network will increase the size of the collision domain. The size of the collision domain can be reduced by adding hubs to a network. The more interfaces a router has the larger the resulting broadcast domain. Adding a switch to a network will increase the size of the broadcast domain. 2. Which switching method describes a switch that transfers a frame as soon as the destination MAC address is read? fragment-free
