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.

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 .
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What wave is combined with another analog signal to produce a unique signal that gets transmitted from one node to another?
Carrier
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation

How is FM transmitted?
the digital signal is converted to analog signal after using by transmitted antenna

Why is analogue a series of pulses?
An analogue signal is not a series of pulses. An analogue signal is a continuous signal which is modulated (changed) in some way to carry information. Common modulations for analogue are Amplitude Modulation (AM), and Frequency Modulation, (FM). There are some others but are not needed here.
What is signal that consists of electrical pulses that represent bits grouped into bytes?
digital
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
Why is reflection of signal useful?
Reflection of a transmitted signal is the basic premise of radar and sonar.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Is this a true statement An analog signal consists of individual electrical pulses that represent bits grouped together into bytes?
no. The answer is digital signal.
How is mobille phones signal transmitted?
Radio Waves
What is RZ Signal?
Return to ZeroA type of digital signal where 1's and 0's are pulses of opposite polarity, but between each bit the line returns to the zero (ground) state. It is rather inefficient in terms of bandwidth/data rate, as each bit transmitted uses two baud (i.e. state changes).
