Guys, please help me! It's urgent.. Thanks!

1.Determine the p.d.f. of a Poisson distribution.

2.Supposing that M represents the mean in a Poisson distribution, how can you determine the standard deviation?

3.Between gas discharge tubes, wind resistance and thermal noise, determine which method will be used by the intel digital random no. generator to generate random bits.

4.In order to reduce the bias that has been developed, use Deskewing method to modify the bit stream. True or false?

5.What can we say concerning the set {x: x N and x is prime}.

6.Given a set [1, 2, 3, 4], provide three subsets of the given set.

7.Determine the appropriate bit rate for a channel containing 1-MHz bandwidth where the 63 is the SNR for the channel.

8.In the above question, determine also the value of the appropriate signal level.

9.Given the definition of the Rho function which is represented as a[x, y, z] a[x, y, z-g(t)], solve for g(t).

10. Give a brief description of the representation of the Pi step function.
