If x(n)=xR(n)+jxI(n) is a complex sequence whose Fourier transform is given as X(ω)=XR(ω)+jXI(ω), then what is the value of xI(n)?

A. \(\frac{1}{2π} \int_0^{2π}\)[XR(ω) sinωn+ XI(ω) cosωn] dω
B. \(\int_0^{2π}\)[XR(ω) sinωn+ XI(ω) cosωn] dω
C. \(\frac{1}{2π} \int_0^{2π}\)[XR(ω) sinωn – XI(ω) cosωn] dω
D. None of the mentioned
Answer» B. \(\int_0^{2π}\)[XR(ω) sinωn+ XI(ω) cosωn] dω
