Abstract: Systems and methods relating to bio-impedance analysis. The system eliminates the need for hardware phase measurements by using the K-K transform to extract the phase from the magnitude detected. The system has a magnitude detection sub-system that includes a signal generation block, a DC cancellation block, and an amplitude control block. An A/D converter converts the detected magnitude into a digital signal and signal processing is performed to extract the phase of the signal from the magnitude detected.
