Question

1) In data transmissions over long distances, what dominates the time it takes for a recipient to fully receive a message for
a. very small messages (what and why)?
b. very large messages (what and why)?

2) Compute the following:
a. What is the effective bandwidth of a square wave that is represented by the Fourier series g(t), with f0 of 15MHz and harmonics of 1f0+3f0+5f0+7f0+9f0+11f0?
b. What is the effective bandwidth of a square wave represented by g(t) with f0 of 7,500Hz and harmonics of 1f0+3f0+5f0?

Explanation / Answer

1) a) propagation time dominates when the messages are very small in size because the transmission size will be very small

B) if message size is large than it depends on the distance, if distance is small comparable to message size then the transmission time dominates, which is the case mostly. Otherwise both will be considered.
