In the (almost old school) NTSC broadcast standard, there are two "flavors" of sync pulses in the TV signal: vertical and horizontal. Recall that the picture is painted on the screen one line at a time. There are 525 lines to paint, and all the odd ones are painted in one "field" and then all the even lines are painted on in another "field" to create the whole picture. The picture is painted on the screen by the electron beam (the "cathode ray"), and the beam needs to be told which line to paint and when to start painting that given line. The vertical sync pulse sets up the beam for a line, and the horizontal sync pulse tells the beam when to start "painting" that line. Then the next vertical sync pulse will "step the beam down" two lines (remember that it's skipping a line 'cause all odds then all evens are painted), and the horizontal sync pulse will cause the beam to begin its sweep for that line. Two sync pulses - vertical and horizontal. Each one arriving to tell the sweep control circuits what line to paint and when to begin painting it. Piece of cake.

What is the purpose for generator synchronising?
The purpose for generator synchronizing is to match the speed and frequency.
When Tim pushes the wire between the poles of the magnet the galvanometer registers a pulse When he lifts the wire another pulse is registered How do the pulses differ?
The pulses differ because the two pulses are in opposite directions.
What is the advantage of ppm over pwm and Pam?
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
If a counter having 10 FLIPFLOPS is intially at 0 what count will it hold after 2060 pulses?
12
What is the significance of Synchronizing Power Coefficient?
The measurement of stiffness of the electromagnetic coupling between the rotor and the stator is carried out by the synchronizing power coefficient. If the value of Psyn is large, the coupling is stiff or rigid. For a too rigid coupling, with change of load or supply, the machine will be under shock which may damage the rotor of the winding
What are composite signals why you needed?
In case of TV broad casting, the Video Signal is not transmitted alone, but it accompanied by a number of other signals or pulses, which help the exact reproduction of the picture at the receiving end. These pulses include Blanking Pulses, Synchronizing pulses and Equalizing pulses. A combination of Picture signal and other Controlling signal or pulses is called Composite Signal. Thus Composite Video Signal may consist of Following Parts.Picture information (Data)Blanking Pulses (Delay Pulses)Vertical and Horizontal Synchronizing Pulses (controlling Pulses)Generally,A Combination of Data and Other Controlling Signal is Called Composite Signal .
Why are synchronizing pulses transmitted along with the picture signal?
To keep the picture locked on the screen, without the synchronization pulses it would become unstable and roll, shift, and tear making the picture impossible to view.
Equalizing pulses in TV are sent during?
vertical blanking.
What has the author Elden Robert Vanderburg written?
Elden Robert Vanderburg has written: 'Frequency stability standards for television synchronizing generators and methods of measurement' -- subject(s): Electronics
Is tv remote electronics device?
Remote controls very much an electronic device. The electronics read button pushes and convert them into streams of pulses. The pulses are sent to a light emitting diode (LED) where they are turned into light. Therefore the link between the remote control and the television is a purely optical one.
Can you put the word synchronizing in a sentence?
They are synchronizing their steps while walking together.
How is infrared light used in remote controls to transmit signals to electronic devices?
Infrared light is used in remote controls to transmit signals to electronic devices by converting electrical signals into infrared light pulses. These pulses are then sent from the remote control to a receiver on the electronic device, which decodes the pulses and carries out the corresponding command, such as changing the channel on a TV or adjusting the volume on a stereo.
What is the form of signal in fiber optical?
To the naked eye - usually not much. To an oscilloscope (and some gadgets) it'll look like a series of pulses. To the appropriate equipment, those pulses can be anything. TV, music, a voice conversation, financial transactions.
What is a sentence for the word synchronizing?
Your song is really great. But you might have to work on your synchronizing skills.
How would you use the word 'synchronizing' in a sentence?
We will be synchronizing our watches in one... two... three... NOW! Don't you just LOVE to watch swimmers that are synchronizing their movements in the water?
Is infrared radiation used in remote controls for tv?
It seems so. Any way it is electromagnetic wave which could be modulated with digital pulses.
What is the best way to do programming?
If you're programming and synchronizing both your TV and VCR you're going to want to follow the specific instructions for your models. There might be different menu options to follow for each, so make sure the instructions are followed.
