###### Informal Development of Fourier Series (CHAPTER 11.05)

Determination of W^P: Part 3 of 4

###### Topic Description

The computation of the complex number $W^{P}$ associated with a pair of companion nodes (node $k$ and node $k+\dfrac{N}{2^{L}}$; where $L=1, \, 2,\, ...\, , \,r-1$; and $N=2^{r}$) can be conveniently explained by expressing the node index $k$ in BINARY NUMBER. Step-by-step numerical procedures for the computation of $W^{P}$.
