Question 1 Consider the following sequence. Fini Not yet answered Tir 111000101111000 Marked out of 14.00 P Flag question Sketch its waveform using the following line codes methods: On-off signaling Bipolar NRZ Unipolar RZ AMI Manchester code Differential Encoding b- Seven message signals each of bandwidth 7 kHz are time division multiplexed and transmitted. Determine the signalling rate and the minimum channel bandwidth of the TDM channel. C- Four channels are multiplexed using TDM. If each channel sends 200 character/s and we multiplex 2 bit per channel, each character is of 1 byte, and 2 synchronizing bit is added to each frame. Find the size of the frame, the duration of the frame, the frame rate, the bit rate for the Windclink, and the bit duration of the link? SLU
