2. (a) Assume that a channel occupies a bandwidth of 110 kHz. We need to combine eleven [01] channels into a link with a bandwidth of 1.26 MHz, from 1 to 2.26 MHz with 5 kHz guard band. Show the configuration, using the frequency domain. (b) Explain the mechanisms for handling the different input speed in Time Division [02] Multiplexing. (c) Ten sources, two with a bit rate of 8 Mbps, four with a bit rate of 2 Mbps and four [02] with a bit rate of 1 Mbps are to be combined using TDM. If the unit size is 10 bits determine the following questions: i. Input bit duration ii. Output bit duration iii. Frame rate iv. Bit rate Page 1 of 2
