What is a digital TV amplifier?
Digital TV amplifier is a device designed to strengthen the signal of the received TV from air -free, also known as a terrestrial signal. The aim is most often solved by problems caused by a weak signal leading to interference or even missing channels. Occasionally, a digital TV amplifier can be used if aviation is shared by more channels in the house.
In principle, a digital television amplifier is required for the same reasons why an analog TV amplifier is required: Home is in a position where the roof antenna cannot be strong enough TV reception to display a complete image. In practice, houses that have been able to survive without analogue amplifier can still be digital broadcasting. This is because television working from a weak analog signal can usually still show a picture, although the one with distortion or "snow" on the screen. With digital TV is much faster decrease-from good picture to this with "blocs" of interference and then to no channel acceptanceu.
In order to complicate matters, digital television broadcasting channels at doses, sometimes known as the Mux, each channel in the dose shares the same frequency. Depending on the location and the nearby transmitter, the TV does not have to receive all doses on the same force. This could mean, for example, that television lifts the perfect signal for 24 channels, has serious interference on six channels and cannot completely pick up another six channels. TV owners must therefore check all of the channels to be sure if they can benefit from a digital television amplifier.
The most common form of amplifier is the one that sits between the air cable coming into the property and the TV set. Better results can be possible by connecting the amplifier directly to the Aerial Itself base, although it requires roof access and usually includes professional installation. These amplifiers should not be confused with distRibal amplifier TV. It works in the same way as the standard internal digital TV amplifier, but aims to replace the loss of strength when the antenna signal is divided between multiple TV sets. It does not have to provide sufficient amplification if the owner of the house has more TV sets and poor air income.
Although less common, it is possible for the TV signal to be too strong than too weak. This can cause digital TV problems, especially if a strong signal for one dose of channels "excludes" a weaker signal for another dose. The solution in this case is not a digital TV amplifier, but rather a attenuation. Although they use slightly different methods, it is an efficiently reverse amplifier and reduces the signal strength.
