Question No.1:          

                                                                                               

Consider a noisy channel in which the value of the signal-to-noise ratio is 2500

and the channel capacity according to Shannon Capacity formula is 33840 bps.

Find its bandwidth? Provide your answer with full calculation and correct unit.

 

 

Calculation

Bandwidth with proper Unit

 

 

 

 

 

Question No. 2:

                                                                                                           

Suppose a signal travels through a transmission medium and due to some

reasons its power is reduced to quarter. You are required to measures the relative strength of this signal before and after power loss. Provide your answer with full calculation and correct unit.

 

 

Calculation

Relative signal strength before and after power loss with unit

 

 

 

 

Note: Give you solution with all relevant calculations in given tables.
