Seventeen sources, four with a bit rate of 400 Mbps, eleven with a bit rate of 200 Mbps

and two with a bit rate of 100 Mbps are to be combined using TDM. If the unit size is 20

bits determine the following questions:

a. How this can be achieved?

b. Frame size

c. Output time slot

d. Bit rate


Ten sources, two with a bit rate of 80 Mbps, four with a bit rate of 20 Mbps and four

with a bit rate of 10 Mbps are to be combined using TDM. If the unit size is 10 bits

determine the following questions:

a) Input bit duration

b) Output bit duration

c) Frame rate



Assume that a channel occupies a bandwidth of 90 kHz. We need to combine eleven

channels into a link with a bandwidth of 1.09 MHz, from 1 to 2.09 MHz with 10 kHz

guard band. Show the configuration, using the frequency domain.


Assume that we are given a task which is split into three consecutive parts. The last two cover the 20%, 28% of total contribution respectively. It is seen that if the first part is made faster by 10%

and the 2nd part is changed in such a way that the overall system is improved by 23%, then what was the change of the second component?


Assume that we are given a task which is split into five consecutive parts. The first four cover the 15%, 16%, 10%, 11% of total contribution respectively. If the 1st part is slowed down 1.5 times, the 3rd part is sped up 30% and the 4th part is slowed down 1.2 times, how much improvement/deterioration is caused by these changes?


1. We need to use synchronous TDM and combine 20 digital sources, each of 100 Kbps. Each output slot carries 2 bits from each digital source, but one extra bit is added to each frame for synchronization. (a)What is the output frame rate? (b)What is the output data rate? (c) What is the frame duration? (d) What is the output slot duration?

2. Two channels, one with a bit rate of 190 kbps and another with a bit rate of 180 kbps, are to be multiplexed. How this can be achieved? What is the frame rate?

3. Explain the necessity of multiplexing.
