First,a design rule for single-parameter biorthogonal wavelets is described,which helps to balance the regularity and filter length of wavelet filters,and thus improves their frequency characteristics.
Upon the top-down design rule,a behavior model of this chip was created during the upper level designing, by using the standard Hardware Description Language VHDL,and a behavior-level virtual computer enviroment was developed on the basis of the model.
A systematic design plan about resource database of manufacturing industry based on internet was introduced,characteristic and design rule of the system were discussed and the key technology was described.
The realization method and design rule for OADM are given. The key technical problem and solving method are introduced. The experiment results of long distance transmission by use of the OADM are given.
The determination of the number of the pair of gears was discussed in basic group and transmission ratio exponent of the first extended group in the variable speed system with asymmetrical mixed common ratio,and the design rule was given.
Combining the calculation method of disc motor and permanent magnet motor and the result of 3D magnetic field calculation, the design calculation method of disk coreless PMSM based on Halbach array is summed up. Then the motor is optimized using the field-circuit combined method and the optimizing design rule is summarized. Lastly software for electromagnetism calculation is compiled.
This paper deals with the determination of the number of the pair of gears in basic group and transmission ratio exponent of the first extended group in the variable speed system with symmetric mixed common ratio, and gives the design rule and actual example of the system.
