摘要:
The present invention is an apparatus and method for performing a &pgr;/4-DQPSK baseband modulation based on a signal mapping to be simplified. The apparatus mainly comprises a memory unit and as processing unit. The memory unit stores a plurality of parameters and their corresponding tabular data of a low pass filter, and the parameters and their corresponding tabular data are simplified in advance. The low pass filter is used for reducing the bandwidth of the apparatus and increasing the utilization of the bandwidth. The processing, unit bases on the input digital data and the tabular data in the memory unit to generate a digital in-phase signal In and a digital quadrature-phase signal Qn.

A multi-domain vertical alignment liquid crystal display (MVA LCD) has a plurality of pixel electrodes for defining a plurality of pixel units. The pixel units are disposed in matrix arrangement, and each of them has a first electrode, a second electrode, and a third electrode. When a voltage is applied to said pixel electrode, the first electrode and the common electrode have a higher absolute voltage difference than the second electrode and the common electrode. The third electrode and the common electrode have the lowest absolute voltage difference.

摘要:
A controller capable of preventing spread of computer viruses is provided. The controller includes a microprocessor unit, and a first interface unit, a second interface unit, a comparing unit and a filter unit which are coupled to the microprocessor unit. The first interface unit is coupled to a storage medium, and the second interface unit is coupled to a computer host. The comparing unit determines whether data read form the storage medium by the computer host is an automatic executing file. And, the filter unit replaces the read data with a predetermined data and transmit the predetermined data to the computer host when the read data is the automatic executing file. Accordingly, the controller is capable of preventing the spread of the computer viruses designed in an automatic executing file.
