题目

英语翻译
Predefined signals recognition:Each predefined signal is emitted by loudspeaker A.Robots
have to signal any detected sound immediately.After a short break,the signal is emitted
by loudspeaker B,and after another short break it is emitted by loudspeaker A and B
simultaneously.Afterwards,this sequence is repeated once.The overall sequence is
the same for each predefined signal.So for two predefined signals it would look like
A,B,AB,A,B,AB,A’,B’,A’B’,A’,B’,A’B’ where ’ denotes the second predefined signal.

答案

预定义信号的识别：每个预定义的信号由扬声器A发出.机器人对任何检测到的声音必须立即发出信号.短暂停止后,该信号
通过扬声器B发出,再次短暂停止后由扬声器A和B同时发出信号.此后,按照该顺序重复一次.每个预定义信号的整体顺序
相同.因此,两个预定义信号的情况如下： A,B,AB,A,B,AB,A',B',A'B',A',B',A'B',其中'表示第二个预定义信号.
