What is video amplifier?
It is a low-pass amplifier that has a bandwidth that ranges from 2 to 100 MHz. Common uses for a video amplifier are in television receivers,cathode-ray-tube computer terminals, and pulse amplifiers. The function of a video amplifier is to amplify signals that contain high-frequency components without any kind of distortion. Current video amplifiers use specially created integrated circuits. With one chip and an external resistor that controls the voltage increase, it is probable to make a video amplifier with a bandwidth of 50 to 100 MHz having voltage increases ranging from 20 to 500.
