A scart connector is a 21 pin rectangular connector that carries video, audio and control links between video recorders, DVD player etc and televisions. They have been popular for many years in Europe but are now giving way to HDMI as the new digital video interface becomes the accepted standard.
As with all analog video signals, the video signals carried by the connector are designed as a point to point signal. Splitting a video signal and connecting to two inputs will load the signal and reduce the voltage level of the signal at both inputs. At best, this will reduce the image quality and may cause the image to fail completely. Although it is unlikely to damage the source equipment, it is not recommended practice.
The audio content on the other hand can be split and taken to two inputs without any noticeable change to the audio performance.
The best way to split a signal on a scart connector is to take the video content through a video distribution amplifier. The amplifier will then drive each of the inputs correctly and retain the voltage levels required. Although many television stores will not stock VDAs, they can be found though most audio visual dealers either online or local stores.

Explian the behavior of difference amplifier?
I assume you mean a differential amplifier. A differential amplifier has two outputs, and two inputs. One input may be grounded out, so there is only one apparent input. When a signal is applied to the non grounded input, it is amplified at one output. The circuitry causes a negative ampification at the other output, so the two outputs taken together give double the output as opposed to using just one.
Why the peak value in double ended differential amplifier is double the peak value of single ended differential amplifier for the same input signal?
The peak output value in a double ended differential amplifier is double the peak output value of a single ended differential amplifier for the same input signal because there are two outputs, one being the normal output, and the other being the inverted output. Whatever the normal output does, the inverted output does, but with a reverse sign. As a result, if one output has a value of X, then then other output has a value of -X. If you compare the two outputs, then, the difference between them will be 2X, or double the value.
What is a cavity combiner in a communication system?
A Cavity Combiner is a device which allows the outputs of two or more transmitters on different frequencies to be combined. It uses bandpass filters on each input to prevent the signals from the other transmitters from entering the output of a transmitter.
Full subtractor using 2 half subtractor?
The half adder is an example of a simple, functional digital circuit built from two logic gates. A half adder adds two one-bit binary numbers A and B. It has two outputs, S and C (the value theoretically carried on to the next addition); the final sum is 2C + S.
What will happen if you connect outputs of two TTL gates directly?
floating state
How do you determine whether a table of input output data is a function?
If every input has an output. If two outputs are the same, they must have the same input.
What is Tri-state logic?
Electronic logic uses just two states, high and low voltage, or "1" and "0". The output of a gate will always be at one value or the other. This is convenient when only a single output is used to drive a signal. In some cases, it is useful to have two or more outputs driving the same signal line. However, if two outputs are linked together, if they have different outputs, there is likely to be damage to the outputs and the level on the line will be un-predictable. A tri-state output has the same high and low levels as standard logic outputs but it has a third state, namely high impedance. A high impedance state means that the output is not transferred to the line so effectively, the output is simply turned off. Another logic gate can now drive the line and the level is entirely predictable. Numerous outputs can now drive a single line as long as only on is turned on at any time.

Why are there Two different outputs on a 3-way signal splitter?
Yes, on a RF splitter there are 2 outputs and 1 input, for certain applications, it can be used in reverse to combine 2 inputs into 1 output!

Can you join two scart leads?
yes - get a scart coupler see http://www.tvcables.co.uk/cgi-bin/tvcables/scan/ml=6/sp=rs4/se=scart/se=extension/se=lead.html
How can you tell if a relationship is a function?
U can see if there is and input that can go into two outputs if there is it's not a function if there is and imput that only goes in to one output it's is a function
How do you connect one speaker to the Right and Left outputs of a stereo amplifier?
To connect one speaker to the right and left outputs of a stereo amplifier, split the input into two parts. These should go to the left and right signals. The input of the amps should be a stereo input.
Does a TV need a scart connection to use a Freeview set top box?
A Freeview set top box is a digital television receiver for use in the UK and delivers analogue signals at the output, for use with analogue televisions. All Freview receivers have video and audio outputs and normally these are found on a scart connector, the European multi-pin AV interface. If a television has no scart connector, it may be possible to use separate video and audio connectors, normally phono or RCA sockets. If the television doesn't have any kind of video input, then the only option is to use the RF connection. Not all Freview units have an RF output. If the Freeview signal must be taken into the television, then the receiver must have the output signal encoded to RF. Note that some Freeview receivers have an RF output but only to loop through the antenna signal and do not deliver the digital programme to the RF output. To be sure that it will work, you must ask the question "does the output of this receiver feed the RF output?" Remember that many salesmen will not know the answer to this, may say yes to get the sale and you get a unit that doesn't work. If that happens, you are fully entitled to return the unit and get a FULL refund as long as you asked the question before you bought it. (The Sale of Good Acts make complete provision for this). This isn't meant to be an attack on salesmen by the way but I have a big problem with poorly trained sales staff gicing out incorrect information!
How is it possible to have more then one output number or each input number?
You will get that if the relationship that you are studying is not a function. For example, for each person, you record the ages of their parents when the person was born. That gives two ages (outputs) for each person (input). Or you could record the height and mass of each pupil in your class: two outputs per person.
What are the difference between NOR gate and XOR gate?
Truth table of 'NOR' is 0 0 - 1 0 1 - 0 1 0 - 0 1 1 - 0 NOR is just opposite of OR as the name itself suggest NOR is the not of OR. Whole XOR is 1 for different outputs and 0 for same outputs.
