WebThe MR signal can be represented as a vector with real ( Re) and imaginary ( Im) components recorded from the I and Q channels respectively. An equivalent/alternative representation of the signal is as a complex number. Signal = (Re, Im) = Re + i Im. where i² = −1, the imaginary unit. Its magnitude and phase can be calculated by simple ... WebThe FFT returns a two-sided spectrum in complex form (real and imaginary parts), which you must scale and convert to polar form to obtain magnitude and phase. The frequency axis is identical to that of the two-sided power spectrum. The amplitude of the FFT is related to the number of points in the time-domain signal.
