With the amount of equipment in home entertainment centers today the need to be able to vary the gain of the audio or video signal is needed. It can give 3 outputs from one input
it is based in three transistor. With this circuit we can amplification selectively the high signal of picture frequencies [Video] with result bigger clarity than this.
Useful to amplify and distribute video signals with low noise and without losses. The CA3100 is a fast opamp designed to amplify video signals with low noise and without losses.
