What bits are encoded by the following Manchester-encoded sequence? n (b). Why is there no ambiguity as to whether the first transition is a clock transition or a data (1-bit) transition? (c). Give an example of a signal pattern consisting of an NRZI encoding of 0-bits and 1-bits that does not contain two consecutive 0-bits and which is not a valid Manchester encoding of data. Such a pattern could thus could be used as a special non-data marker.
