Vibration control of MR whole-spacecraft under medium–high frequency …
To compensate actuator time-delay, and consider the system's nonlinear characteristics under medium–high frequency and small amplitude conditions, a gray prediction time-delay compensation method is proposed based on the human-simulated intelligent controller (HSIC). After verifying through simulation and experiment that actuator time-delay ...

Diode and very small amplitude high frequencies signals
(simulated with a voltage source) has a weak amplitude (around 100 uV) and a high frequency (around 600 Khz). The issue is that the current after the diode does not get rectified. The output current is very weak (less than 250pA) and still contains the full sine signal (both halves of signals).

Half wave rectifier at high frequency and small amplitude …
When the frequency of the input voltage is very small then we get a very low amplitude of output voltage as shown in fig. below. we know that the reactantce of a capacitor is $frac{1}{j omega}$ i.e. at low frequency the reactance of the diode capacitance becomes very high. As a result we get a very low output amplitude in low frequency.
