a. Given the bit sequence “00000000”, draw the corresponding waveforms for all three unipolar codes.


a. Given the bit posteriority "00000000", attract the similar waveforms for all three unipolar codes (NRZ, RZ, NRZ-I) shown in Figure 6.5.

b. For each waveform, estimate the DC (average) voltage.

c. For each waveform, estimate the dullness of transitions.
