This is the video amplifier circuit with splitter, it is designed to amplify the video signal, compensating for the loss of signal because this signal will then be split up to three outputs. The output signals may be used in television monitors, recording at the same time several DVDs, etc. .. The advantage of this circuit is that it is quite cheap, easy to build and the results are very good. Splitter and Amplifier Video Circuit Diagram The video amplifier circuit has a maximum gain ratio of only 4 times the impedance is 75 ohms on the input and output, and wide bandwidth of this circuit is 5 Mhz adjust VR1 1. Adjusting VR1 until the voltage at the base of Q1 is equal to one volt. And is the voltage drop across R7. (No input signal). Approximately 0.75 volts. 2. Adjust VR1 in the middle Enter the input signal is 1 Vp-p, then adjust VR2 to have the lowest rate of increase. Then turn on the TV or monitor to the output and then adjust VR1 until the test signal to be applied without disto...

The circuit was designed to provide distribution, extension and splitting of personal computer video output to two or more monitors. Super Video Graphics Array (SVGA) – defined in 1989 as a set of graphic standards that supports 800 X 400 resolution or 480,000 pixels with support for 256 colors or a palette of 16 million colors. Pixel – short for picture element, is the smallest point or single item of information in a graphic image and the basic unit of programmable color on a computer image or computer display. 2N3906 – a common PNP BJT transistor intended for medium voltage, lower current and power, which can operate at moderately high speeds, used for general purpose switching and low-power amplifying applications. The circuit may also be called as video port expander, multiple monitor, PC video splitter, LCD Y splitter, etc. It provides the same high resolution image to several monitors using a single PC. Each line of the SVGA card of the analog output stage of PC contains 75 ohm ...
