Which device converts digital signal into analog signal?

Which device converts digital signal into analog signal?

The correct answer is Modem. Modem, (from “modulator/demodulator”), any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.

Which device converts digital signals to analog and vice versa?

In general terms a data converter is a device that converts analog signals to digital data or vice versa. Devices that convert digital signals to analog are called DAC.

Which of the following is used to convert an analog to digital?

The most common technique to change an analog signal to digital data is called pulse code modulation (PCM). A PCM encoder has the following three processes: Sampling. Quantization.

What hardware is needed to convert the digital signal of the computer to signals that can be transmitted through telephone lines?

modem
A modulator-demodulator, or simply a modem, is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.

How can we convert analog signal to digital?

ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the ADC are its sampling rate and resolution.

What is the name of a device that converts digital and analog signals?

A modem is a device that translates digital signals from a computer into analog form so that they can be transmitted over analog telephone lines.

What devices use digital signals?

Computers, CDs, DVDs are some examples of Digital signal. The digital signal bandwidth is high.

Why do we convert analog to digital?

An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by minimizing errors.

Why do we need to convert analog to digital?

What is the old name of Internet?

ARPANET
This eventually led to the formation of the ARPANET (Advanced Research Projects Agency Network), the network that ultimately evolved into what we now know as the Internet. ARPANET was a great success but membership was limited to certain academic and research organizations who had contracts with the Defense Department.

What part of the phone converts analogue and digital signals?

circuit board
The back of the circuit board The analog-to-digital and digital-to-analog conversion chips translate the outgoing audio signal from analog to digital and the incoming signal from digital back to analog.

Are digital signals more powerful than analog?

This type of electronic l signals can be processed and transmitted better compared to analog signal. Digital signals are versatile, so it is widely used. The accuracy of the digital signal is better than that of the analog signal.

What do you call a device that converts analog data to digital?

In general terms a data converter is a device that converts analog signals to digital data or vice versa. Devices that convert analog signals to digital are frequently referred to as ADC. Devices that convert digital signals to analog are called DAC.

How is analog information transmitted in a modem?

Analog information is transmitted by modulating a continuous transmission signal by amplifying a signal’s strength or varying its frequency to add or take away data. A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines.

What’s the difference between a data converter and ADC?

In general terms a data converter is a device that converts analog signals to digital data or vice versa. Devices that convert analog signals to digital are frequently referred to as ADC.

Which is the best description of a network cable?

The physical environment (typically a cable) through which data travels as it moves from one component or device to another. No physical constraints confining the signal to a set path (wireless). the most economical and by default the most popular choice among networking cables.
