For real valued time signal, Fourier Transform has conjugate symmetry The Fourier transform of a conjugate symmetric function is always (a) imaginary

- o) = X*(w) From this it fol- lows that the real part and the magnitude of the Fourier transform of real- valued time functions are even functions of frequency and that the imaginary part and phase are odd functions of frequency In other words, linear scaling in time is reflected in an inverse scaling in frequency
