Why does length x width work for finding area?
That is the definition of the area of a rectangle. It does not work for any other shape.
Which is the amount of work done in a certain amount of time?
This is the definition of power (measured in Watts). Power= Work/Time
Is funky two-step a stipulative definition?
is funky two-step a stipulative definition. stipulative definition means the establishemet of a new word or the use of a previously used work in a novel way.
If force is work divided by distance then distance is force divided by work?
I usually start with the definition of work: Work = force * distance so... Force = work / distance Distance = work / force So, no. You had it backwards.
Why does the links in what is the definition of a uniform cross-section don't work?
Maybe because it is old
High definition signal analog tv?
A number of years ago, in the early days of consumer HD television there was an analog high definition component signal format available. Since then, manufacturers and content publishers have agreed that HDMI is the only HD interface to be available on equipment. Although the signal interface also carries audio and other data on a single cable, it does not benefit the consumer. It is unlikely that any other analog interface will become available for HD signals. There are a number of adapters that can accept HDMI signals and deliver an analog signal, normally in the form of a VGA signal. Some work better than others but many can be adversely affected by HDCP (High bandwidth Digital Content Protection) which can prevent the signals being converted to their analog form.
Will a high def DVD player and DVD work on a regular tv?
Most Blueray high definition players have an analog output that delivers standard definition signals. If a high definition disc is played, the output will normally provide an SD version of the content. Using the analog output means that it is possible to use Blueray players on SD televisions. When an HD television is installed, the HDMI port can be used to obtain HD video. Before purchasing a Blueray player, check that it has an analog output and that it provides a down converted signal of HD material on the analog ports.
Why digital signals are more noise free than analog signals?
Digital signals are "forced" to be either 1 or 0, whereas analog signals are not. This means that a signal of 0.8 will be pushed to 1 in a digital signal and will remain 0.8 in an analog signal, and 0.2 will be 0 digital and 0.2 analog. This means that in order to overwhelm a digital signal the noise must do much more work to be effective. digital signal have only two states analog have infinite states therefore more susceptible to noise
Are the modem and the codec functional inverses ie could an inverted modem?
No, the modem and codec are not exactly the functional inverse of each other. teh modem converts the digital data to analog signal by teh modulating part of it. teh demodulating part of the modem can be used to covert teh ANALOG SIGNAL to digital data....but this analog signal will be modulated analog signal. the coding part of teh codec convert teh analog signals to teh digital signal .these analog signals are pure analog signals. Hence teh codec and modem may seem as functional inverses but do not work as so due to teh fact dat the demodulating part of the modem used only the modulated analog signal and cannot process the pure analog signals .
Comparison between ADC and DAC?
An ADC, or analog to digital decoder, is used to "translate" analog signals into digital signals. An analog signal can take on any value, such as 0.1V, 0.5V, 4.12V, 5V and so on. A digital signal on the other hand can either be "high" or "low", 1 or 0. A computer can only work with digital signals, and therefore you need to convert an analog signal into a digital signal in order for the computer to be able to work with it. This is what you do when you record sounds or music. Sound is an analog signal and had to be converted with an ADC to a digital signal before it can be used in a compter or stored on a CD. A DAC, or digital to analog decoder is the oposite of the ADC. Here the digital signal is converted into an analog signal. This is what happens when you play music from a CD-plate. On a CD there are a number of holes, which each translates as a 0 or 1. These are read with a laser beam which is reflected back into a receiver whenever the laserbeam hits a hole. This then counts as a 1. When the disk is spinning it produces a stream of 1s and 0s, which togerther form a binary string, such as 00010111011101. The DAC then converts this value into a analogue signal, such as 1.1V, which is then used to power your speaker and produce audible sound.
How does a modem work on osi physical layer?
Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. That is the definition of Layer 1.
How does modern work for computer?
you mean modem? MO-DEM MOdulation / DEModulation. It turns your digital signal into analog, so it can go thru the phone lines to your isp, and then from the phone lines to their server, it converts the analog signal back into digital.
What is an Internet phone?
Internet phone conforms to Internet protocol. Analog phone can work with digital line by connecting a ATA into it. ATA is a connector or device that will convert analog signal to digital signal making standard phone an IP phone.
Can a Blu-ray disc play on a High-Definition TV?
Yes it can and needs an HD television to be seen in the best quality. A Bluray player will also work with standard definition televisions using the analog outputs they usually have. The content will only be seen in standard definition of corurse.
Why the received signal in analog communication is distorted by the channel noise than that of digital communication?
If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low
How does a DAT drive work?
Hi, It's very similar in operation to a VHS VCR, except that it reads and writes a digital signal as compared to an analog signal. Hope this helps, Cubby
Can you use old antena with converter box to get HD on your anolog tv?
For most people, their old antenna will work just fine. Don't let the people at the electronics store fool you, there is no such thing as an "HD antenna." There is nothing special that needs to be done to an antenna to receive HD signals. In fact, many of the antennas that are being marketed as "HD antennas" are inferior UHF-only antennas that receive a smaller set of signals than your old antenna. However, some people who were barely receiving an analog signal may need to buy a better antenna. Also, if the location of the digital transmitter has changed or the signal strength of the TV station has changed, you may need to re-aim or replace your old antenna. Simply plug the old antenna into the converter box and then plug the converter box into your old TV where the antenna used to go and you will be fine. The converter box will tune in a digital station (some digital stations are HD, some are not) and convert the digital signal into an old-fashioned analog standard definition signal and feed it into your old analog TV. You will not be able to watch shows in HD on your old analog TV, but you will be able to watch a version of the HD broadcast that has been converted into Standard Definition (SD) for you. You will be able to watch all of the digital stations including the HD ones but you will see them in Standard Definition. Standard Definition is 480i. Digital to Analog converter boxes receive all tv transmissions of 1080P , 1080i , 720P , 480P , 480i and coverts them ALL to 480i to watch on a standard definition NTSC Analog TV.
