|
|
Carrier modulation
|
|

|
|
NRZ encoding

Question 950 Explanation:
In the Manchester encoding , a logic 0 is indicated by a 0 to 1 transition at the centre of the bit and a logic 1 is indicated by a 1 to 0 transition at the centre of the bit. Note that signal transitions do not always occur at the ‘bit boundaries’ (the division between one bit and another), but that there is always a transition at the centre of each bit.
Correct Answer: C
