NEED HELP ! Explain/show calculations. Thank you!

1. (Given : bandwidthfigure out sampling rate)Suppose I have an analog signal that has as its highest frequency 2KHz. Assume that I sample this signal at twice its highest bandwidth.

A ) What is the sampling rate (How many samples per sec)?

B) Suppose each sample is codes using 8 bits. What is the size ( in bits) of each sample produced?

C) (given sampling rate + bits per sample --- figure out bit rate) What is the bit rate produced by the sampler?

D) Explain the conversion of analog bandwidth to digital data rate.
