I would like a favor from networking forum members i can't find answers to these questions

 

Q1. Why it is necessary after the modulation in multiplexing the Bandwidth of the signal should remain same as before the modulation?

 

Q2. Why Synchronous Time Division Multiplexing is not efficient? And why Statistical Time Division Multiplexing is efficient? 

 

Q4. Why we need addressing for each output time slot in statistical Time Division Multiplexing?

 

Q5. Why the capacity of the link is normally less than the sum of the capacities of each channel in statistical Time Division Multiplexing?

 

Answer to any of these will be helpful.

Q2 You can find all these answers on Google *Note* select the first link to answer this question.

 

 

Edit: Thanks for the questions, I had to look that first one up since I had no Idea. I learned something in the process!
