Page 3 of 5 det 2. a) Suppose, Grameenphone has 10 voice channels, each of 60Kbps. They use synchronous TDM to multiplex these channels. If a character at a time is [10] multiplexed (a characters in each output slot), 1. Draw the first two output frames with arbitrary inputs. II. What is the size of an output frame in bits? III. What is the output frame rate? IV. What is the duration of an output frame? V. What is the output data rate? VI. Input bit duration? VII. Output bit duration? VIII. Output slot duration? b) Suppose that we have 4 sources who participate in a synchronous TDM [5] multiplexer and that combines only three characters from each user at a time. [Note that the characters are sent in the same order that they are typed. The first source is silent.] Draw the necessary frames with the appropriate contents using the Interleaving concept of TDM. a a. Source 1 message: b. Source 2 message: SUCHQUESTION c.
