Definitions
- the method can't be.
- the filter is pre-filtered and obtained.
- the factor is updated in the root of the largest absolute F a eLev update factor
- the filter is filtered by the root filter to filter the sheep, and the filter is filtered before the filter.
- the filter filter is filtered before, and filtered. It makes it possible to see if there is a phenomenon that has improved. Description
- the method provided by Liben includes the maximum absolute F a eLev update factor in step 10;
- Step 103 The waver is ahead of the tiger.
- Step 01 Search for the largest cannon in the front F a eLev where Kawe ev B U 0 ..159, where k is before
- the different factor C is updated. Take a break) If F a eLev T is, the fast increase factor C, ie CC 10 B), F a eLev T is not, but is very close to this, factor C, ie C) TF a eLev T is not, and the amplitude is not large. This fast factor C is CC. ) T F a eLev, not , and the amplitude is small, keeping the factor C not, ie C. In and in the factor update, the pre-factor C is inside, 0 ⁇ 0
- Step 0 Since the solid in the middle of the system may exceed [ , ], the amplitude is large, and in the end, the final result is still not high. Thus, in, In a step-by-step manner, it is possible to perform self-gain control so that it is always in the system. Gain control
- the self-gain control factor is determined by the previous factor, ie . .
- the gain update factor is also determined by the factor.
- C indicates the magnitude, if the C force rises rapidly and C C 4, then you can make it.
- 0.5 represents fast to the desired gain C fast rise zWR ⁇ , then you can make 05+0.4 -0.75 4, which means fast to the desired gain; upper 0.99 represents the desired gain.
- T represents the factor ⁇ , in which the gain of the gain of the T) gain control factor includes the gain control G obtained by the upper gain control factor and the previous gain control factor.
- the domain can be domain + x , where the fish in the N force (in the N 1 ) can also be obtained in the remainder or other methods. Gain, get the most gain
- step in step 0 the step above, can eliminate the phenomenon of the final letter, and get better.
- the method provided by Yu the step by step can be The line is self-gain controlled, and the most outstanding signal elimination phenomenon is better.
- Method includes
- Step 1 Step 1 Step 0 Phase
- the step is preceded by the factor gain control factor, ie ⁇ t.
- the gain update factor which is also determined by the factor.
- C indicates the amplitude, if the C force rises rapidly C ⁇ T, then you can make 0 for fast to expected gain; C for fast rise and CR ⁇ , then you can make o 05+049* C -075)"4, Representing rapidization to the desired gain; Outside of God. 0.99, representing the expected gain. Which shows the same factor C, in this T 0. Step 0 Before using the filter to lose
- the gain control is s , s 1 s 159 ⁇ 1 compared to the previous one , the present is the energy and in the same step , in the Hugh can be
- the method provided by this method can obtain better signal elimination from the final and self-gain control.
- the method of control provided herein provides a means of control, the steps of which may be in the apparatus.
- Self-power gain control factor sheep 1 root factor self-gain factor
- T T T is not represented by the same magnitude as 2 T T 2
- X is taught by the factor A of the factor C above the update rate of the factor C ⁇ ⁇ A ⁇ A ⁇ .
- the filter is an all-pass filter, and the filter is a function of the all-pass filter
- the filter parameters , , the factor before C. Filtering the sheep before the root filter
- the former gain control factor, the self-gain control factor, and the factor before C are the new gain factors.
- the gain control factor and the gain control factor of the gain at the root of the gain 0 are the gain control G ⁇ ⁇ ,
- the gain of the sheep 0 rests on the root of the gain control factor and the former self-gain control factor domain gain gain control
