  signal switching
A distinctive feature of the proposed device is that an increase in the input power level leads to the signal switching from one to another output, which is caused by a power-dependent variation in the spin wave phase shift.
      
With these applications of the delay model the opposite impacts of capacitive and inductive coupling in different signal switching patterns are illustrated with reference to the work of Kahng, Muddu, and Sarto.
      
Although both uncertainties prohibit the solution to timing analysis on a wire being a single signal switching, we do not treat them in the same way.
      
General purpose small signal switching diodes such as 1N4148 are normally adequate.
      
In general, it's a better solution to handle output signal switching during long constant signal periods by a proper software implementation.

SPWM(Sinusoidal Pulse -Width Modulation) inverter is increasingly widely used in P.R.China's machinery industry. To improve its performance for better economic efficiency,one thing that needs to be done is to compensate for time delay effects.What I mean by compensating for time-delay effects is that the parts of output voltages corresponding to low -order harmonics are almost completely suppressed.This compensation is accomplished through our specially designed circuit as shown in Fig. 5.Eq.(4)is used for computing output voltages of fundamental component(n =1)and significant low-order harmonics(n= 3,5,7).Our compensation can make B3,B5,and B7 in eq.(4)almost zero.A1(the total output voltage of fundamental component)in eq.(4) depends on voltage modulation ratio p and motor power angle Fig.3a shows the variations of A1 with μ for = 0°, 30°, 60°and 90°.Fig.5 shows that wave form after compensation (Fig. 5b) is also somewhat improved over that without compensation (Fig. 5a).
