Its structure is easy to see, it is used to separate the device brightness and color output. Why do this? This is designed primarily to overcome interference composite output video program when the luminance and chrominance. Luminance signal bandwidth of radio and television in general is 6MHz, while the domestic standard PAL color signal bandwidth of 1.5MHz. Composite video output signal is 4.43MHz chroma subcarrier wave frequency is placed between the video luminance signal, the computer button on the remote board line classification, chroma demodulation display output, the chroma subcarrier from the composite video signal filtered out, the computer button on the remote plate line model, so it is possible to lose the luminance signal frequency 4.43MHz ± 0.75MHz and reduces the level of clarity. In addition, not completely filtered chrominance subcarrier may interfere with the luminance channel, whereas in the edge of the luminance signal is entered 4.43MHz chroma demodulating circuit, both interfere with each other, reducing the quality of the broadcast. Using S-Video output luminance and chrominance separation can improve the picture quality, which is why some people call it "High Definition output" reasons. (5) The construction of each phase wire connector not staggered, in a unified section will lead to accidents such as a cotton ginning factory stack one mobile crane truck had illegally use wire connector into the library unloading, computer keys remote control panels line type, pull off the wire joints between the joints phase short circuit, spark, causing jute burned, causing a serious accident five, long-term open joints loose some joints in the placement quality is better, but because of thermal expansion and contraction of the reason , or long-term experience vibration, will loose connections such as electrical wiring within a bridge bridgehead, because the vehicle often produces violent shock when the bridge, so that slowly loose wire joints, contact resistance gradually become larger, fever Yulai more serious, leading to a fire six, conductor coupling at oxidation and corrosion in moist air ecology, it is easy to generate oxide layer (on the copper wire will show copper oxide conductor, easier to generate the aluminum wire alumina) This function poorly conductive oxide for example, electroplating factory workshop, lead the long-term corrosion by acidic air, the external structure of the oxide layer conductor, computer keys remote control plate line, causing the contact resistance increases, resulting in a high temperature after power severe redness thanks to the wire and even feel real time, then it did not turn into an accident computer keys remote control panel cable accessories _ Xu Song Chong electronic products factory _ computer keys remote control panel line is composed of Dongguan Shijie Xu Chong-electronic products factory provided. Dongguan Shijie Xu Chong-electronic products plant (chuangxs.1688.com) (www.chuangxs.1688.com) Dongguan, Guangdong, connectors leaders, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs. Song Chong-wook in electronic products factory leadership with the staff warmly welcome all inquiries negotiations to create electronic products factory Song Chong-wook better future.
