Because of video's complex nature, AM lends itself to transmitting several different signals simultaneously, like video, chroma, sync, etc. and it can provide the bandwidth required to do it easily.
FM for the audio has a bandwidth of 100 khz, and FM is much better for that. It's also a `cleaner signal`, but the FM transmitter has limitations on how much information it can carry.

∙ 14y agoIn Amplitude modulation, only the amplitude of the carrier wave is changed in accordance with the intensity of signal.However, the frequency of modulated wave remains the same,
i.e, carrier frequency.This takes place in transmission of picture.
And, in Frequency modulation ,only the frequency of the carrier wave is changed in accordance with the signal.That is why in sound wave transmission FM is used.

∙ 12y agobecause FM used only for one Perticular Frequency where as in video signal amplitude vary time by time so,FM cant be used for video signal.

Difference between analog video and digital video?
analog video is generally a type of video form in which we have numerous waves in terms of crests and troughs in a continuous manner upside-down on X axis whereas, in digital video we have many bars that are upawrds and then downwards on X axis in a continuous manner that also includes two types of binary bits, either 0 or 1.
What is the correct HTML element for playing video files?
The video tag can be used for it. The tag was introduced in HTML5 only.
What are signal conditioners used for?
Signal conditioners are used for a variety of purposes. They can be used as amplifiers, electrical isolators, exciters, and cold junction compensators.
What is a burst gate amplifier?
It is used to separate the color burst signal from the color signal.
Does a repeater reduce the effects of attenuation for a digital transmission signal?
It depends on the repeater. Those that receive a signal, buffer it in real time and pass it on as a digital signal will reduce the effects of attenuation. Those that receive a signal and regenerate it with a new clock signal will generally eliminate the effects of attenuation completely.The type of repeater used depends on where and how it is used as well as the signal that is being transmitted.
What term is used to describe a neuron that is not transmitting a signal?
When a neuron is not transmitting a signal, it is at rest.
What term is used to describe a neuron that is not transmitting signal?
When a neuron is not transmitting a signal, it is at rest.
What is the function of the amplifier in a transmitter?
used to increase the power level of the transmitting signal
Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
What PIN is used for transmitting a positive signal on an RJ-45 straight-throughpatch cable?
1
What is Extender setup help?
Extender is used to extend the coverage area of your WiFi network. It works by receiving your existing WiFi signal, amplifying it and then transmitting the boosted signal.
What is the use of video amplifier?
Usually to amplify the video signal across long distances of cable. This is necessary to maintain quality and consistency of the video signal in runs of 100 ft. or more. The word "video" means wideband. A video amplifier is used for any wideband signal.
Why inTV broadcasting video signal is trancemitted in AM but audio signal is in FM?
AM was used for the video signal because components to transmit and receive the video signal (tubes, originally) were not available that could modulate the frequency fast enough for the amount of information required for a video signal. The VHF band, where most of television broadcasts resided until the the adoption of Digital Television (DTV) was also being used for FM audio broadcasts.
Does s-video have audio signal?
S-video is an interface standard for video signals only. It used two cables, one for a black and white image and the other for the color information. Audio needs to be routed on separate cables.
What is an S video cord?
An S video cord is used in video systems that separate the luminance and chrominance portions of a video signal and carry them through separate cables within the S video cable. Composite video has both of these items contained within the same signal. By keeping the circuits separated, the color and picture quality is improved as compared to a composite video signal.
How do you make wireless modem with gsm sim used?
A wireless modem can be made with a GSM Sim card and a compatible cell phone. The GSM signal is made available to the surrounding area by transmitting an 802.11G/N signal.
What is average signal power?
Transmitting any signal requires energy. "Power" is energy per time unit; for example, if 10 mJ are used for the transmission every second, then the power is 10 mW. "Average"... Well, presumably the amount of signal power can change over time, so the average is taken for a certain time period. For example, when transmitting 1's and 0's, it may be that transmitting a "1" requires more energy than transmitting a "0" (depending on how the information is encoded); the average in this case would be taken with the assumption that the same number of 1's and 0's are transmitted in the long run.
