Why is digital technology preferred to analog technology in communications technology?

Why digital communications and what its advantages over analog communication ,first you have to know what is the difference between analog signal and digital signal. Analog signal analog signal is continuous time signal i.e. it has a value at any moment of time and it has infinite number of valus , such as dinusoidal signal ,you can substitute X with any value and you will have an value in Y in the follwing sin relation Y=sin(X). 1-Noise and destortion immunity:-when analog signal is transmitted in free space for long distances it will be distorted and no an ideal recovery done in receiver to recover the exact signal which transmitted ,but in digital communication digital signal consist of 2 levels only zero or one (not like the analog one , it has infinite numbers of values or levels at each period of time),so digital signal can be recovered easily and excactly like transmitted one. Hint : Device that used to pattially recover the analog signal after a certain distance is called repeater ,from its name it receives transmitted analog signal and filter it and amplify it and transmitt it),but in digital transmission it is different ,the device used for recovering digital signal which transmitted from acertain distance is called regenerative repeaters ,it receives transmitted digital signal and recover it to regenrate a new exact signal like received one then retransmitt it for further distance. 2-More privacy and security due to encryption. 3-Error detection techniques can be used and correction as well. 4-Easy for processing and applying multiplexing techniques. 5-Low cost. 6-Transmission rate can be changed easily. 7-Digital hardware implementation is flexible and permits the use of micrprocessors, digital switching elements and layer scale.

What replaced analog technology and added support for text messaging?
The digital technology replaced the analog technology and added support for text messaging.
What are the two main types of technology?
There are basically ONLY two types of wireless technology: analog and digital. ALL "wireless" technology is radio technology.
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 is the term for a device that converts digital data from a computer into analog signals and back again?
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.
How do you swap change the digital dash to analog in your 85 thunderbird?
by using some of the converters we can swap the analog dash into digital
Which communications technique combines digital and analog technology to transmit data?
the digital carrier loop system
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
Are CD's digital or analog?
CDs are created and utilize digital technology.
Why digital transmission is preferred than analog transmission?
Faster responce.
What is the difference between analog and digital communications?
Analog means continuous transmission of data whereas digital means discrete transmission of data. In analog communications we are transmitting finite amount of data in infinite amount of information. so,there is a possibility of occurrence of noise. where as in digital we are transmitting finite amount of data in finite amount of information. so , out of these two, digital is most efficient.
What replaced analog technology and added support for text messaging?
The digital technology replaced the analog technology and added support for text messaging.
Are digital phones as reliable as analog phones?
Digital phones are more reliable than analog phones. The digital signals are easier to produce and the technology is more reliable than that of analog signal.
What are digital converters used for?
Digital converters are used to convert an analog input into a digital current. They also have converters that covert from digital to analog. These are used for older model TVs that need to take a newer digital technology input but the tv still requires analog.
Why was analog technology replaced with digital technology?
This transition was viewed as critical to the cellular industry's competitiveness
What is a communications process that allows the modem of a sending machine to convert a signal from digital to analog?
DEModulating
Was earlier satellite technology digital technology?
A communications satellite is an artificial satellite stationed in space for the purpose of telecommunications. The first satellite launched was the Sputnik I and it weighted about 180 pounds. That launch ushered in new political, military, technological, and scientific developments and it was not digital at all. Analog was the stile back then.
What technology was introduced in the 1990s that will eventually replace analog television?
digital tv
