The results are obtained through this processing with 28 VDC of decreased pull-down voltage,almost 7×10~5 times of the switch lifetime,0.8 μs of the lowest switching time,0~0.5 dB of the insertion loss and 35~45 dB of the isolation loss under 10 GHz.
Simulation results show that the proposed system has a rapid switching time of 25 μs,which meets the requirements of the personal mobile system(PHS) standard. The synthesizer has a 1.8% frequency tuning range from 1.615 GHz to(1.645) GHz.
When it is transmitted by the FH (Frequency Hopping) system, the analog signal is lost. After evaluating the result of our experiment, the voice quality restricted by channel switching time and hopping rate is discussed. The result can be used in choosing channel switching time and the hopping rate design a frequency hopping system.
Based on the analysis on protection process protecting optical transport network in the condition of failure,one lower limit model for evaluating the protection and switching time is shown and validated.
Furthermore, the impact of time interval and switching time on the solution of the optimal control is investigated.
The values of important switching parameters such as the threshold field for switching Es, holding current and voltage Ih and Vh, switching time τs, delay time τd and recovery time τr are presented.
At the switching time we switch the harvesting rate from h to some transitional control u?, then to 0.
The main difference with respect to the previous works in literature is that our optimal harvesting policy is a piece-wise continuous function of time t, at the piecewise point tc, which is called switching time.
The essential conclusions of this paper include a condition for a single switch, that is, when the saver will decide the switching time, prior to retirement, to start saving.
