Why is the colour sub carrier located at the higher end of the video bandwidth?

∙ 12y ago
The original NTSC enhancement to support color mandated that black and white television sets be able to receive a color signal and display it as a black and white signal. Thus, all of the color information was placed at the top end of the video spectrum, and it was encoded in such a way that a non color sensitive Y decoder could still see the black and white portion of the signal without any problem.

What is advantage of lower bandwidth?
The reason for using lower bandwidth is that not all Internet users are able to download and use programs, videos, etc., with high bandwidth. In some cases the higher bandwidth files become corrupted or they stretch the resources of satellite and dial-up systems. Operating at a lower bandwidth provides an advantage because it solves such problems.
Which signal has a wider bandwidth a sine wave with a frequency of 100 hz or a sine wave with a frequency of 200 hz?
The signal that changes at a higher rate occupies greater bandwidth.
Need of modulation in communication?
Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities
What property of modulating frequency is varied for frequency deviation?
FM is the carrier property when terms like `frequency deviation' are used. Unlike AM, which has a single frequency, and the frequency is modulated by increasing the amplitude of the frequency, with FM, it's the frequency itself that is changed, either by making the frequency a bit higher or lower from the actual stated frequency. For instance, a FM radio station located at 100.00 on the dial will have the frequency deviate by plus or minus 75 kilohertz (+100.075 HZ or - 99.925 HZ.) or more commonly referred to as a bandwidth of 150 KHZ. for 100% modulation.
How Frequency Modulation Have Higher Bandwidth then AM?
Bandwidth is defined as difference between two frequencies.In AM only amplitude is modulated or changed to transmit the data at the given fixed frequency. In FM the frequency of the signal is changed to transmit the data. Since we will need a range of frequency to transmit the data using FM (say frequencies from f1 to f2), the bandwidth of FM signal will be higher than AM signal which can transmit at a fixed frequency.But.....The above answer does not address the issue of "strength of modulation", that is, modulation index.A.M. will always have a bandwidth of twice its highest modulating frequency regardless of the strength of modulation.For voice comms with about a 3 kHz maximum frequency, A.M. will demand (3+3) = 6 kHz of bandwidth.Because F.M. modulates the frequency swing of the transmitter, low modulation indexes with F.M. can give a bandwidth LESS than the maximum modulating frequency. Narrow-Band F.M. (NBFM) can have a bandwidth of *less than* 3 kHz, indeed it can have a bandwidth of only a few hundred hertz, in theory.In practice, very narrow NBFM suffers from worsening signal-to-noise ratios, and one of F.M.'s chief advantages over A.M. is the superior signal-to-noise of F.M. when it is allowed sufficient bandwidth.
Is low bandwidth signal has more power than high bandwidth signal?
no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.
Does a powerline router give you good bandwidth?
They do give you higher bandwidth capabilities for your networking.
Why Microwave SDH Radio can not go beyond STM 1 bandwidth?
It can. 167 Mbps of user's business traffic on a single duplex carrier is quite common now, as are several higher data rates.
Which pulse systems requires higher bandwidth?
pam
For what type of internet user upload bandwidth is be much much higher than download bandwidth?
This in ADSL technique.
What is a higher bandwidth?
Bandwidth refers to the amount of data that can be transmitted at the same time so a higher bandwidth would mean a greater amount of data can be transmitted per second. Bandwidth is often confused with speed, but should be thought of as the number of lanes on a highway not the speed of the vehicles that travel on the highway. An increase of bandwidth would be like a greater number of lanes on a highway.
Is ddr2 slower than ddr3?
DDR2 is slower than DDR3 due to their difference in bandwidth. DDR3 has a higher bandwidth hence can transfer data at higher speeds than DDR2.
What do mean by high bandwidth?
The biggest difference between high and low bandwidth is latency. The lower the bandwidth the more time the computer spends trying to download the data.
What does a Broadband speed test do?
A Broadband speed test measures not only the speed of a web connection but many of them also measure the bandwidth. The higher the speed the faster the internet. The higher the bandwidth the more load the network can take.
What can be use to improve the bandwidth of Voip?
VoIP doesn't have bandwidth, it uses bandwidth. To improve your bandwidth make sure you have an up to date modem and that you are subscribed to a large enough amount of data transfer from your ISP. Typically 1Mbps or higher is sufficient, but try for 3 Mbps minimally.
Does bridging connections affect speed or bandwidth?
No if your have a higher band wideth that can stand to have these connected.
What is advantage of lower bandwidth?

In some cases the higher bandwidth files become corrupted or they stretch the resources of satellite and dial-up systems.
