    Suppose a length-16 sequence x[n] needs to be reordered in bit-reversed order ,then it is used as an input to a FFT algorithm.The sample number of the sequence in bit-reversed order is: A: [img=583x69]1803a2f846ecc71.png[/img] B: [img=581x71]1803a2f853645c7.png[/img] C: [img=583x77]1803a2f85f65a12.png[/img] D: [img=598x77]1803a2f86c48c3f.png[/img]

    翻译:Jobs had always proved himself a genius in everything he did. Merely listing his achievements was sufficient explanation of why he was Fortune’s CEO of the Decade. Over those 10 years alone he had radically and lucratively reordered three markets—those of music, movies, and mobile telephones—as his impact on his original industry, computing, had only grown.
