Study Switching for Frequency of Pilot Beacon on CDMA Network Optimization

Adjusting the switching frequency at which the signal is time-division transferred, the basic frequency signal is transferred through n branches within one signal cycle efficiently, and each branch works for a fixed 1/n of the signal period.

In this paper,first of all,we study the stabilization of the switched linear systems composed of stable subsystems by means of the switching frequency.

According to the analysis of computer audio and video signals, the circuits of center control module, VGA switch module, audio switch module and volume regulate module have been given in detail, meanwhile the work principle is also expatiated.

In this paper,we introduced the video and audio switch system of multimedia central controller which based on ARM,present the principle、design project、software model and hardware model of multimedia video and audio switch.

The crucial technology is discussed such as channel switch.

Introduces the usage of hardware and software in integrating the supervision alarm and video switch in the 8031 microcomputer using the example of supervision alarm system in banks.

A kind of easy, applied and low cost computer audio/video switch circuits have been introduced.

Combined with the application of the video monitor system in the Shangjie Freeway two key techniques-video switch and video capture are studied.
