Description

M242955 V. Creation Instructions (1) [Technical Fields of New Types] This creation is to provide a TV capture card, especially a TV card used in a notebook electric moon. 'The mediator is connected to the circuit board and used The cable sends the TV signal to the mediator, so that the TV capture card can be connected to a specific location preset in the pen-type computer. [Previous technology] Press' Current general entertainment home appliances such as TV, VCD, VD , Audio, etc., and other home appliances have gradually been replaced due to the rapid development of electrical technology, households no longer need a lot of entertainment, electrical products, only a desktop computer can solve life It meets the needs of vision and hearing, and compared with ordinary home appliances, the computer is just like a group of home appliances. Whether it is watching TV or listening to music, it can be screened by electricity to show its advantages. The entertainment effect brought by, and the development of the computer ^ positive, rapid progress, from the desktop computer to the notebook computer, can be two = 彳 二 & music to carry, including the issue of TV cards The exhibition is also very important. The characteristics of a notebook computer = entertainment for watching TV, and the pen is thin and short, even: = 可 ', so its development also tends to worry about the thickness of a circuit board ^ mm),- The proportion of space occupied is also very important, such as device (such as microchip circuit board surface connection), C. . Cbillc〇n Tuner socket, # 用 #, etc.), and when a connection is set at one end of the circuit board to make the octopus-type computer, simply insert the interface card into the bus' " the connection socket on the surface card is fixed to the computer On the housing

Page 5 M242955 V. Creation instructions (2) The docking station receives the computer's screen to broadcast the vertical confluence so that the height of the adapter is used to create a few cards for the creator. When using a notebook computer, you need to consider the connection of the zero-view card. The volume placed in the specific socket is 50 TV signal lines', so it must be as relevant as the industry [new content, so multi-party evaluation and continuous trial circuit board winding (a) voltage

The brain used for note placement is also thin, short, and thin, but this type of internal electromagnetic wave computer is the impedance of the line and the impedance of the connection impedance in the brain. The banks are all type computers, that is, because of the characteristics of the bus bar and turning down, the connector is connected to the TV. It is used for note components. It has a lot of interference. Therefore, it is necessary to connect the cable and the signal connector. The topic of external wiring and connection is to do this. Depending on the signal, and put the received signal, but the desktop power strip 'makes this way impossible 11 turn the TV card to landscape orientation and affect the notebook computer light,' after thinking, and then develop a profitable computer The TV card can only be used. Due to the limited space of the notebook, the socket cannot be directly connected to the note position due to signal transmission between the pieces, and because of the 50 ohm (small), all current notebook electrical ohm (Ω) impedance connections are used. 7 5 Ohm (Ω) How to solve the problem of resistance manufacturers with different impedance values is eager to study and improve = Yes: In the above problem 'is to collect relevant information, pass the test, and work in this industry to accumulate and modify, and then research out mines嗝 七 嗝 & ^ Heart] The principle of the connector and electricity of TV out of nine and summarized into the following points: Standing wave ratio: It is the helmet method when the connector's cable or circuit board is wound: it must be compatible 'The TV south frequency signal that originally belonged to analogy will be easily mismatched. 5. Creation instructions (3) The head note sets that electrolysis produces ghost images or completely loses digital signals on some channels.' Depending on the design stage of the high-frequency signal, the voltage standing wave ratio must be considered.: A complex circuit design must consider the overall inductance, capacitance, and resistance coefficients. If the impedance does not match the signal matching, the problem of signal attenuation and reflection will occur. And noise ratio: In TV high-frequency signals, it is necessary to maintain a balanced 75 ohm (Ω) impedance # match under the overall circuit. Jit signal must pass through the PC board, which is 1. 00mm thick; The width of the layout line must not be greater than 50mm, so there must be good grounding protection at the periphery of the road. Electricity is based on the above-mentioned TV signal connection type summarized by his research in order to design such a type that can be used in Pen 1 You wronged the new patentee of the capture card. The main purpose of this creation is to # 丨 罐 努 你 Φ, mesh up, sending the TV signal to the decoder with a cable, so that the TV capture card can be far away Connected to I jj reversely connected to the special position preset in the Weiji computer. The secondary purpose of this creation is to connect the 50 ohm (Ω) cable with the 50 ohm (Ω) TV in the brain. The key to signal line matching Reached the use of the pen S 创作 this creation-the purpose is = use the electric device to weld in the through slot to become the second office through the slot on the road board, so that the adjustment of the TV card will reduce the height of the TV card four
