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.
Difference between analog and digital control systems?
An analog control system is one that presents data by measuring a continuous variable. This reports the data back in voltage or pressure.
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.
What is the difference between analog data and wireless data?
Analog data can be send through a wire = wired data Analog data can be send through the air = wireless data). "Wireless data", as in: "data travelling through the air" is always analog because it propagates as a continuous EM wave through the air
What Technology used to modify analog signals to make them suitable for carrying data over a communication path?
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
What is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
Difference between inband and out of band signaling?
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
What is Analog carrier system used in telephony?
Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.
What does digital cable mean?
Digital signals permit greater transmission of data over analog signals. The URL http://telecom.hellodirect.com/docs/Tutorials/AnalogVsDigital.1.051501.asp has quite a bit of useful information on the differences between analog and digital broadcasting
What is the alteration called when digital or analog signals are altered to represent binary data?
Modulation
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.
Why digital signals are better than analog signals?
according to my view, to deal with digital signal is more easy then that of analog. and it also stable so many of the semiconductor circuits run only on dc signals...... i think doubt is clear now....
