Extracted text: We need to use synchronous TDM and combine 20 digital sources, each of 100 Kbps. Each butput slot carries 1 bit from each digital sources, but one extra bit is added to each frame for synchronization. Answer the following questions: a. What is the size of an output frame in bits? b. What is the output frame rate? c. What is the duration of an output frame? d. What is the output data rate? e. What is the efficiency of the system (ratio of useful bits to the total bits).
