What is a modems purpose?
1. To MODULATE (convert) the digital signals from a computer into analogue signal to enable it to be carried through the telephone line. 2. To DEMODULATE (convert back) analogue signals from a telephone line into digital signal to be used in computer.
Which device is used to convert analog signals to digital signals?
In datacommunications this is a modulator/demodulator, commonly known as a modem. In electronics a digital to analog converter (DAC) chip is used to convert digital signals to analog and an analog to digital converter (ADC) chip to convert analog signals to digital. Some chips are available which include both ADC and DAC functionality. There are thousands of different types of DAC and ADC sytems and which one to use largely depends on how fast you want to do the conversion.
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
Which device converts a digital signal to text?
A: If the signal is analogue then an ADC analogue to converter is required. The output will be in a digital form and that can be decoded and displayed as readout using LEDS or any other visual media
What is the function of zero order hold?
Zero order hold is used in Digital - Analogue converters (DACs). It literally holds the digital signal for the sample time, then moves to the next digital sample and holds that signal for the sample time as well, in order to reconstruct the analogue 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
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
What purpose does a vga to HDMI serve?
VGA to HDMI cable convert an analogue signal to a digital signal. It does this by connecting an audio cable to the adapter, where the video signal is fused with the audio also, so there is only one cable connecting to your HDTV.
Why is it necessary to convert a analog signal into a digital signal?
Because digital is in now
Why do mobile phones need the anologue-to-digital and digital-to-analog chip?
All digital devices that produce audio out put IE CD player / dab radio have a digital to analog converter chip, all sounds you hear are analogue if it were in digital all you would hear is just high pitch screeching no matter what sound you are listening to, it would be like hearing Morse code speeded up thousand fold constantly, phones transmit a digitally signal, there for when you speak into it it has to convert your analogue voice into digital to transmit then convert it back to analogue so you can under stand.
Where does the name modem come from?
It is a device that changes the digital signal from a computer into the analogue signal more suited to a phone line, and the analogue signal from phone line into the digital signal for the computer to use. These two processes are called modulation and demodulation. The word modem comes from these two words: MOdulation and DEModulaion = MO DEM.
