Best Answer

The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters.

A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well.

Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.

What is the transfer of digital or analog data using digital or analog signals?

The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.


What are Modems used for in Internet?

Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...


Why the information collected by the sensor can't be read by computer directly?

A computer cannot read data from sensors directly because the signals received from the sensors come as analogue signals which, a computer cannot read. It requires a converter to convert the signals in to digital signals so the computer can be able to read it.


What is digitizer in computer graphics?

Digitizer converts analog or physical input into digital images. This makes them related to both scanners.


Are the modem and the codec functional inverses ie could an inverted modem?

No, the modem and codec are not exactly the functional inverse of each other. teh modem converts the digital data to analog signal by teh modulating part of it. teh demodulating part of the modem can be used to covert teh ANALOG SIGNAL to digital data....but this analog signal will be modulated analog signal. the coding part of teh codec convert teh analog signals to teh digital signal .these analog signals are pure analog signals. Hence teh codec and modem may seem as functional inverses but do not work as so due to teh fact dat the demodulating part of the modem used only the modulated analog signal and cannot process the pure analog signals .

Is a modern an output device?

A "modem" is considered a transceiver. It receives data, and sends data. But it also converts signals in the sense that it can be seen as a DAC (digital to analog converter) and a ADC (analog to digital converter). Most dialup, DSL, and cable modems are examples of that - they plug into your computer and converts from-and-to your ISP the data you're receiving and sending. The signals you send from your computer are typically digital and the modem converts them into analog ones.
