How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
Which device in pstn willl convert analog to digital?
You would utilize a VoIP adapter in the conversion of analog voice signals into digital IP packets. These adapters also have the ability to convert digital IP packets into analog voice streams.
Is there an existing product that can be used in combination with a copy machine that would digitize hard copy x-rays?
yes!
How is voice communications converted to digital signals?
The human voice is an analogue signal because the frequency of the sound varies in the sound waves as well as their amplitude that gives the power. Analog signal is defined as a signal that has a continuously varying amplitude or frequency. Human speech, and everything else a human hear, is in analog form.
Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
Voice signals are signals whereas computer signals are?
Voice signals are analog signals, whereas computer signals are digital .
How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
Why do you convert voice signals to electrical signals?
becoz persons voice s very different from other animal . so voice is converted to electrial signal
To what frequencies within the spectrum do voice signals belong?
lasers
Why is Voice communication an output device?
Voice Communication is Interexchange of Voice that is Capturing Sound to Electric Signals and Generating Sound from Electric Signals. Voice Communication needs both Input Device (Microphone) and Output Device (Headphones\Speakers). Broadcasting Voice Communication entirely depends on Output Devices at Audience Side.
Can all the signals be categorized either as even or odd signals?
all the signals can not be categorized as even and odd,signals like voice we can not categorize it as even or odd either we can say it is a complex signal.
Name the device that is used to regenerate data and voice signals?
Repeater
What is a digitize tablet?
It's a device that converts hand writing or drawing to digital signals usually with a stylus or pen. Good for writing Chinese or Japanese characters. It's another way of inputting data or commands to a computer.
What does 'VOIP' mean in telecommunication?
VOIP means Voice over Internet Protocol. Basically, voice signals traversing over the Internet.
Systems that use Voice over Internet Protocol VoIP convert voice signals into for transmission over data networks?
Binary packets
What makes microphones make your voice loud?
A microphone, by itself, does not make your voice loud. It changes the sound waves your voice makes in analogous electric signals. These signals can be sent to an amplifier and speakers to make you voice sound loud. The amplifier increases the amplitude of the electric waves so that when they are sent to a speaker and changed back into sound waves, they will be louder.
What are necessary devices used for voice chat?
Headphones or speakers and a microphone. Whatever program that is providing the voice chat could also be considered a necessary device.
