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?
An FM Tranceiver, is a FM Radio that can tranmitt signals and receive signals.

Why power amplifier used in FM transmitter?
Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
Why SSB is not suitable for video signal transmission?
Single Sideband (SSB) modulation is generally not suitable for video signal transmission due to its inherent complexity and the nature of video signals, which require a substantial bandwidth to accurately convey high-frequency details and rapid changes in luminance and chrominance. SSB is designed for efficient voice communication, where the bandwidth can be constrained, but video signals contain a wide range of frequencies and require continuous transmission of large amounts of data. Additionally, the SSB demodulation process can introduce delays and distortions that are unacceptable for real-time video applications. Hence, modulation schemes specifically tailored for higher bandwidth and quality, like amplitude modulation (AM) or frequency modulation (FM), are preferred for video transmission.
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?

What type of modulation is used in tv transmission?
Television transmission primarily utilizes amplitude modulation (AM) for the video signal and frequency modulation (FM) for the audio signal. In analog TV, the video is modulated using AM, while the accompanying audio is transmitted using FM to provide better sound quality and resistance to noise. In digital TV, various modulation techniques such as 8VSB (for ATSC) or COFDM (for DVB) are used to efficiently transmit data over the airwaves.
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.
