MIL-STD-1553 uses __________ encoding so the clock can be recovered from the data.
Answer: B
Correct answer: Manchester
Manchester biphase encoding places a transition at the middle of every bit, so the receiver sees an edge at a known point in each bit period and can lock its own clock to the incoming data.
No separate clock line is therefore needed. A second property matters as much: the signal has no DC component, which allows the transformer coupling the standard's stub connections depend on. The cost is bandwidth, the signalling rate being twice that of a code without guaranteed transitions.
