synchronous timedivistion multiplexer

In the following synchronous time-division multiplexer, each TDMA frame consists of one bit taken from each input plus one framing bit. Sketch the output frames, clearly showing the frames and its contents. Use "F" to represent the framing bit and use "X" to represent an empty slot. You should assume that the input is taken from the right hand side of each bit-stream. The output frame is also formed right-to-left and framing bit is the leftmost bit. What is the output bit rate? If the multiplexer in figure1 performs statistical multiplexing and the data rate of the output is maintained to be 20 Kbps, sketch the output frames. Ignore any framing or addressing bits, and clearly describe how the output frame is being constructed.
