5.5 Analysis of Signal Response

From the viewpoint of communication engineering, a ferroelectric capacitor is a nonlinear and, as a consequence of hysteresis, time variant system. Consequently, standard approaches for the analysis of signal response in linear time invariant (LTI) systems cannot be applied. Instead a more detailed analysis of the properties is necessary. Actually, any signal response shows a strong dependence on shape, amplitude and frequency of the input signal.
