Plot the spectrum of the output samples what is the 3-db


Problem

Generate a Rayleigh distribution with a 100-Hz fading bandwidth. A suggested approximation is to filter white Gaussian noise samples at 1 kHz with the one-pole filter yn = 0.7yn-1 + 0.3un. For the output samples,

(a) Plot the distribution of the output samples. Does this change with fading rate?

(b) Plot the spectrum of the output samples. What is the 3-dB fading bandwidth?

(c) How much of the lime is the signal -4d13 or lower? How does this time compare with the-oretical values?

(d) Determine the average 3-dB fade duration. That is, each time the signal drops 3 dB below average, how long does it stay 3 dB or more below average?
