How could you use the statistical loading data available from an intelligent multiplexer to determine if the vendor's literature concerning its efficiency in comparison to a conventional TDM is reasonable?

Figure below shows a multiplexer. If the slot is only 10 bits long (3 bits taken from each input plus one framing bit): i. What is the output bit stream? ii. What is the frame rate? iii. What is the output bit rate? iv. What is the duration of each bit in the output line? 101110111101 300 kbps 11111110000 Frame of 10 bits 300 kbps TDM 1010000001111 300 kbps 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. i. What is the size of an output frame in bits? ii. What is the output frame rate? iii. What is the duration of an output frame? iv. What is the output data rate? v. What is the efficiency of the system? (ratio of data bits to total bits) Assume that 5 sources, 2 with a bit rate of 20 kbps and three with a bit rate of 40 kbps, are combined using multiple slot TDM with no synchronizing bits. i. What is the size of a frame in bits? ii. What is the frame rate? iii. What is the duration of a frame? iv. What is the data rate?
