What type of data does Bluetooth use?
Digital data sent over UHF radio frequencies.
Where should analog to digital converter be placed?
where an analog signal is to be converted into digital signal,because in some applications we need digital signal where we have analog signal that is we use an A/D converter
Should you use UHF antenna with digital converter box or VHF?
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
Will the new digital signals be in both UHF and VHF?
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
Why analog signal convert into digital signal?
Because an analog signal takes up more bandwidth than the new digital format. By cutting off the analog signals and offering digital only, it frees up enough space on the network to offer services to a wider range of people. It also includes enhancements to the providers network. For example, faster internet speeds, more TV channels, and more features.
Does a video use an analog or digital signal?
A video uses the analog signal
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
Does a digital camera use digital signals?
The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing. The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing.
Why do you go for sampling in digital signal processing?
we have to do sampling in dsp because in dsp we have to convert all in analog signal in digital form so for converting into digital signal first we have to convert continuous tome signal into discrete time signal....so we use samplin in dsp...
Can you use your old uhf antenna to pick digital signal on a digital t v?
The answer to the questions depends on where you are. In the recent change to digital in the UK, many existing analog aerials work perfectly with the new service although others have had to be changed. Generally, in areas where the digital terrestrial service is using similar frequencies to the analog service and where there is good signal strength, the old aerial is likely to work. The results will vary between countries and even between areas. Try it and see if your aerial still does the job.
How is digital audio decoded?
To have digital to audio played back it has to be changed back to analog with the use of a DAC or digital to analog converter. The DAC will take the digital signal and try to recreate it as a analog signal.
Is there any difference between an analog signal and a wave signal?
A Digital Signal can have one of two values, 1 or 0. An Analogue signal can have any value between 1 and 0. Digital signals are better for sending information as if the signal is somewhat distorted, it is still easily recognisable. Vinyl Record use analogue. Cds use Digital
