Video fans and professionals in the field will find in this small signal distributor-amplifier an excellent ally when it’s necessary to distribute a single video signal across several equipments. The circuit shown here should have a lot of applications. Basically, the distribution amplifier takes the composite video signal from a video player (VCR) or a [...]
With the astonishingly rapid growth in the market for flat-screen TVs and high-definition TV, many CRT television sets have been consigned to the attic, even though many of them were still working perfectly and could have been used as spare sets in a bedroom or another room, for example. Although all current flat-screen receivers have [...]
Here’s the simple design allows ATV to be transmitted from a low-power (up to about 3W) FM or CW transmitter. Ideally the transmitter should use CW mode and have its ‘key’ down but an FM rig will work just as well if the microphone is disconnected and the PTT switch is closed. The only reason [...]
The GT4123 and GT4123A are the first dedicated single device, two input video mixer ICs available to the professional video and multimedia. Read more for description and circuit diagram. A PC board which uses two GT4123 mixers, two GB4551 back-porch clamps and a GX4314, 4×1 video switch is available from GENNUM. This board can be [...]
This electronic circuit is a video signal amplifier that offers a broad band amplifier with a bandwidth of 5 MHz which will take the video signals from your VCR and will amplify them sufficiently to drive up to 3 monitors, TV sets (provided that they can accept direct video signals), or other VCR’s for recording [...]
Here’s the project was to construct a Composite Video Pattern Generator, which can be used as a teaching tool in the video field as well as a laboratory instrument, useful for repairing and adjusting television receptors. This video generator instrument is in no way intended to be a commercial set, because I cannot guarantee all [...]
