What device converts digital signals to analog signal?

What device converts digital signals to 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.

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

modem
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.

How are digital signals converted to analog?

DACs take a binary number of the digital form of audio and turns it into an analog voltage or current that, when done entirely over the course of a song, can create a wave of audio that represents the digital signal. It creates the analog version of the digital audio in “steps” of each digital reading.

Which converts analog-to-digital and digital to analog?

An analog-to-digital converter, or ADC, performs the former task while a digital-to-analog converter, or DAC, performs the latter. A DAC, on the other hand, inputs a binary number and outputs an analog voltage or current signal.

Which device converts digital signal to analog and vice versa?

Explanation: 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 networking device can convert digital data into analog signals and vice versa?

Modems (modulators/demodulators) are data communication devices that convert digital signals to analog signals, and vice versa. Modems allow digital transmissions over analog telephone lines.

What is communication hardware?

What is Communication Hardware? • It refers to electric device and system for transferring data or information from one place to another. EXAMPLES • MODEM • CABLE • FAXMODEM • ROUTER • WIRELESS TECHNOLOGY o INFRARED o BLUETOOTH o Wi – Fi.

Which converts analog to digital and digital to analog?

What is the need of digital to analog converter?

A digital to analogue converter (DAC) converts a digital signal from the computer into an electrical voltage which can be used to drive electrical equipment, for example, a stirrer motor.

Which device converts an analog signal to digital and a digital signal to analog quizlet?

An analog-to-digital converter, or ADC as it is more commonly called, is a device that converts analog signals into digital signals.

Can you convert digital signals to analog and vice versa?

Which device attached to the computers that converts digital signal to analog form at the sender’s send and does the opposite at the receiver’s end?

» Modem (Modulator-Demodulator) is a device attached to computer that converts digital signal to analog form at the sender’s end and does the opposite i.e. analog signal to digital at the receiver’s end.

What kind of device is needed to convert analog signal to digital signal?

The correct answer is D, “A/D converter.” A digital controller requires a digital signal as its input. A 4–20 mA transmitter outputs an analog signal. Therefore, a device to convert an analog (A) signal to a digital (D) is required.

Can a digital to analog converter be fast?

The conversion rate of such converters is limited only by the bandwidth of the analogue parts of the circuit and the response time of the digital parts of the circuit, and so in principle may be very fast.

How does a digital input affect an analog output?

These voltages may be either 0 (for logic 0) or some supply voltage V cc (for logic 1). The TTL input connected to the lowest value resistor carries more weight than the others, thus, a larger binary or digital input results in a larger analog output voltage.

How is the amplitude of an analog signal modified?

The amplitude of analog carrier signal is modified to reflect binary data. The binary signal when modulated gives a zero value when the binary data represents 0 while gives the carrier output when data is 1.
