Suppose that data are stored on 8.54-gbyte single-sided, double-layer dvds that weigh 15 g each. suppose that an eurostar rail service train, london to paris via chunnel, carries 10 4 kg of these dvds. the great circle distance of the line is 640 km and the traveling time is 2 hours, 15 minutes. what is the data transmission rate in bits per second of this system?

Suppose that you noticed that flying two 60 mile trips was too much for a pigeon and you had to let the pigeon rest for 2 hours before returning. How does the “Winston Channel” compare to DSL under this circumstance?

ii. Time Division Multiplexing scheme is implemented in a channel. The multiplexer in TDM used eight 500-kbps channels using a time slot of 4 bits. a. What is the output of the multiplier if the input to the channel is b. c. 100010101010101000? What is the frame rate? What is the frame duration? What is the bit rate? MEC_AMO_TEM_035_02 Page 4 of 11 iii. d. What is the bit duration?
