1 i. A signal with 200 mill watts power passes through 10 devices, each with an average noise of 2 microwatts. What is the SNRdB? If the signal has a spectrum between 11f and7f and the signal period is 0.5 ms, what will be the maximum channel capacity?
ii. If you want to achieve the same channel capacity in a noiseless channel, what
measures would you take?

2. What are the problems caused by delay distortion? Explain with an example.

3. What is the phase shift for the following?
a. A sine wave with the maximum amplitude at time zero
b. A sine wave with zero amplitude after 3/4 cycle and increasing
