public class Hilbert
extends java.lang.Object

Computes the N-point Discrete Hilbert Transform of real valued vector x: The algorithm consists of the following stages: - X(w) = FFT(x) is computed - H(w), DFT of a Hilbert transform filter h[n], is created: H[0]=H[N/2]=1 H[w]=2 for w=1,2,...,N/2-1 H[w]=0 for w=N/2+1,...,N-1 - x[n] and h[n] are convolved (i.e. X(w) and H(w) multiplied) - y[n], the Discrete Hilbert Transform of x[n] is computed by y[n]=IFFT(X(w)H(w)) for n=0,...,N-1
