Question on analog communication

[FONT=times new roman,new york,times,serif] Hi there hope u can help me out. I am a 3rd year ECE student. This is a doubt from my paper analog communication
please help me out. The following are the 2 problems:

1.Find the function and cumulative distribution function for transmitting 3 digit messages over a noisy channel. The channel has error probability P(E)= 2/5 per digit. The errors are statistically independent from digit to digit. Also plot the frequency funcyions and CDF's.

2. Show that output signal y(t) of a filtered random signal is wide sense stationary (assume any input properly)😎

    You know this all went above my head but I can tell you one thing. You have been one of the few people who know how to ask a question and I encourage others to do the same.

    Anyway, I can say that you look into your text book and try to figure this out, or refer some books on communication circuits ( using OP-AMPS / Schmidt trigger etc) and looking at the mathematic involved there.

    Another thing you can have a look at is this, BUT believe me, I hope you know what you are talking about. Here is a white paper I found on The MAP and cumulative distribution function equalization methods for the speech spectral estimation with application in noise suppression filtering.

    And I have no idea how probability works here, go figure!
