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:
“We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. The king died and then the queen died is a story. The king died, and then the queen died of grief is a plot. The time sequence is preserved, but the sense of causality overshadows it.”
—E.M. (Edward Morgan)
