too late :(

heres the problem:

"A certain communcation channel has a bandwidth of 10 kHZ. If a pulse of 0.5 ms. duration is tranmitted over this channel, determine the width (duration) of the received pulse. Find the maximum rate at which these pulses can be transmitted over this channel without interference between the successive pulses."

Its due in a little bit, so help!

anyone?????

1. Think about it logically and see if the 0.5 ms pulse could actually be transmitted over the channel without distortion.

2. If i remember correctly, this is just a question testing the application of that most famous of all telecommunication laws... (the name of which i have forgotten ;P )

basically, u need double the bandwidth needed to transmit the thing simply because you want to guard against interference.

heat, do your own homework!. hahehhe

10 kHz * 0.5ms is your answer.

haha i don't know

 

[heat23]

well..anything short of the answer isnt gonna help me

DannyLove, that is a sweet site, is that all done in Flash?

 

[heat23]

well in my teacher's lecure notes i have this........

Transmission of pulses through a system increases the pulse duration (BUT BY HOW MUCH??)
IF the impulse resposne of the system has duration tf and pulse had duration th seconds, then the ouput will have duration th + tf (WHATS THE IMPULSE DURATION IN THIS?)
