In mathematics, a polyphase sequence is a sequence whose terms are complex roots of unity:
where xn is an integer.
Polyphase sequences is an important class of sequences and play important roles in synchronizing sequence design.
Famous quotes containing the word sequence:
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
—Walter Benjamin (1892–1940)
