Which device is used to convert analog signals to digital signals?

Answer 1

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.

Answer 2

A video capture card.

This can be a PCI card that slots onto the motherboard, or a USB device that you can plug into a spare USB socket.

The card contains an ADC (Analogue/Digital Converter) processor, which takes the analogue signal via RCA connectors and sents it as serial (USB) or parallel (PCI) to the computer, for further processing and storage.

Answer 3

An analogue-to-digital converter (ADC) is used to convert analogue data into digital data for the computer system to process. A digital-to-anagloue converter (DAC) is used to convert digital data back into analogue data for output.

Answer 4

A component called a digital to analogue converter or DAC, (it does the opposite of an analogue to digital converter or ADC).

Answer 5

The photo diode is coupled to a ADC can be used as a light to digital signal.

Answer 6

SAMPLER is used to convert analog to digital signal.

An analogue to Digital converter, ADC...

Answer 7

digital to analog converters

Answer 8

video capture card

Answer 9

An Analog-to-Digital Converter (ADC).

Answer 10
