Three multiplexing systems are arranged in the configuration shown below. The multiplexers A and B, each has four input channels. The data rate of each input channel is 250 kbps (1 kbps = 1000 bps). Each frame coming out of A or B and into C has the frame size of 32 bits. Each output frame of multiplexer C has the frame size of 64 bits. In all multiplexers A, B and C, sync bit is not used in each frame . Answer the following questions:

a) What is the frame rate (in frame per second) and frame duration (in microsecond) of multiplexer A?

b) What is the output data rate of multiplexer B (in megabit per second)?

c) What is the slot size of each frame coming out of multiplexer C?

d) What is the frame rate (in frame per second) and frame duration (in microsecond) of multiplexer C?

e) What is the output data rate of multiplexer C (in megabit per second)?

Round your numerical answers to 3 decimal places where possible.
