3. (a) What is noise, noise voltage and noise power due to a resistor and why understanding and controlling of noise is critical in telecom signal transmission? Estimate the noise voltage and noise power generated by a 1 MO resistor at RT 40 °C if BW is 18 MHz. Is this noise significant? [Hint: en V 4kT (Bw)R, Pn kT (BW), k 1.38x102 [10] (b) Define channel capacity C and explain how it is affected by the S/N ratio. The...

3. In most communication systems, the noise (X) is treated as an additive Gaussian noise (random2 variable with normal distribution).If the noise mean is equal to zero and the variance is equal to 0.1. Find the probability P(Xs-0.5).
find the noise floor for a 5 Mhz signal, with 10db noise floor at room temp
identify 2 or more sources of noise, and describe a professional or personal example when noise interfered with the ability of the sender of information to successfully deliver his or her message to a receiver of information. Would framing techniques have helped eliminate the noise? be specific and thorough
A gong makes a loud noise when struck. The noise gradually gets less and less loud until it fades below the sensitivity of the human ear. The simplest model of how the gong produces the sound we hear treats the gong as a damped harmonic oscillator. The tone we hear is related to the frequency f of the oscillation, and its loudness is proportional to the energy of the oscillation. Part A If the loudness drops to 80 % of...
