Please Do ALL ASAP!!!!

a)A binary sequence is transmitted over a noisy channel. The sequence is received with a single error. The received waveform is shown in figure below. What is the transmitted binary sequence? (0.5 mark) (11) Name the line coding technique used here. (0.5 mark) (1) Draw the corrected waveform in paper. (0.5 mark) 2 1 0 -1 -2 0 1 2 3 4 5 6 7 8 b) For a bit stream 1011011, draw the waveform of the binary signal and sketch the waveforms for Manchester coding (0.5 mark) (m) Differential Manchester coding (Assume that the signal level for the previous bit at the start is negative) (1 mark)
