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]
