It is desiredto FDM 30voice channels (each with a bandwidth of 4.5KHz) along with a guard band of 0.8KHz. Ignoring a guard band before the first channel and the one after the last channel, what is the total bandwidth, in KHz, required for such a system.

Britney Velez · Answer 1

Total bandwidth required = 158.2 KHz

Explanation:

given dа ta:

number of channel 30

bandwidth of each channel is 4.5 KHz

bandwidth of guard band 0.8 KHz

According to the given information, first guard band and the guard band after last channel should be ignored, therefore we have total number of 29 guard band.

As per data, we can calculate total bandwidth required

total bandwidth = 30*4.5 + 29*0.8

total bandwidth required = 158.2 KHz
