Webwhich is a real number. Some of the basic tricks for manipulating complex numbers are the following: To extract the real and imaginary parts of a given complex number one can compute Re(c) = 1 2 (c+ c) Im(c) = 1 2i (c c) (2) To divide by a complex number c, one can instead multiply by c cc in which form the only division is by a real number ... WebApr 25, 2012 · FFT produces completely real output. For a signal composed of only sine waves, it produces completely imaginary output. A phase shift in any of the signals will result in a mix of real and complex. Complex numbers (in this context) are merely another way to store phase and amplitude.
