Photocoupler

The mini camcorder has an AV output jack that can be connected to a color TV with an AV interface for playback. However, in most cases, the matching RF modulator can be purchased as an optional accessory, so if the color TV does not have an AV jack, it cannot be used. Watch the video directly. This circuit can meet this requirement. The circuit principle is the same as that of a general RF modulator. The circuit can be placed in the appropriate position in the camera's power adapter/charger.
