AM has a smaller sideband bandwidth than FM, since the baseband bandwidth of NTSC video is already about 4.5MHz, using AM vestigial sideband the resulting bandwidth is only just under 6MHz (without partially suppressing one sideband, the resulting bandwidth would have been about 9MHz). Had FM been used instead the resulting bandwidth might have been around 100MHz instead.

Which type of modulation is used in TV transmission?
In television system for video transmission AM is used and for audio transmission FM is used....
Why only AM but not FM used for transmitting video signal?
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.
What is an Antenna FM Trap?
The FM Trap is used to reduce offending FM signals that can cause audio and video interference. Designed to attenuate the entire FM band and Average -26dB. It's a piece of hardware between the antenna and the preamplifier.
What is a FM tranceiver?

What is the modulation used for television broad casting?
The video is AM and the audio is FM.
What is the difference between narrowband FM and wideband FM?
wide-band is used for high quality transmission Narrow-band is used for speech & data k.vijayvardhanbabu
Why FM is used for voice signal?
Analog radio uses either amplitude modulation (AM) or frequency modulation (FM) to carry an audio signal. AM signals can be received at greater distances than FM but they suffer from interference from other stations and a wide range of electro-magnetic sources. FM signals offer better quality with less interference than is typically found with an AM signal. The transmission range is far smaller than AM. For a wide geographic coverage, multiple transmitters are needed although the limited range also makes FM an ideal medium for local stations where long range is undesirable.
Why do FDM/FM microwave systems use low-index FM In microwave radio communications and system gain?
FM/FDM systems are commonly used in microwave wireless communications because they allow for different frequencies to be assigned to different signals, which means that a large number of signals can be transmitted on the same frequency band. This increases network traffic density without interference between different signals. The properly tuned low gain small system provides additional capability to transmit signals without interfering with other signals in the same frequency band. This increases the efficiency of licensed frequency use, allowing for high-speed and higher-quality data transmission.
What is a wireless FM transmitter used for?
A wireless FM transmitter is used to play music files through ones FM radio through wireless connectivity. One can hook up their device and as long as it is set within the proximity of the FM transmission, it will be able to play the music.
Which waves carries AM and FM signals?
Radio waves
