Why is it necessary to digitize voice signals?
To minimize the distortion of analog signals during transmission Because digital lines transmit signals more efficiently across distances than analog lines Because many telephone networks are moving over to digital interfaces
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.
Is a moderm converts the digital signals from a computer into signals that can travel over a network?
Yes, a modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over various types of networks, such as telephone lines or cable systems. It also performs the reverse function, converting incoming analog signals back into digital form for the computer. This process enables communication between digital devices and external networks.
Does Ethernet transmit signals in digital form or analog form?
HDMI is a digital replacement for existing analog video standards, such as 3D, an Ethernet data connection and improved audio and video capacity.
How analog instrument interfaced with a digital instrument?
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
What part of the telephone network depends on analog signals?
In traditional telephone networks, the local loop, which connects individual homes and businesses to the central office, primarily relies on analog signals. These analog signals transmit voice communications over copper wire. While much of the backbone and long-distance transmission has shifted to digital formats, the last mile connection often still uses analog technology, especially in legacy systems. However, many newer systems are transitioning to digital methods for improved efficiency and quality.
7 What term is used to describe the transformation of analog signals into digital signals?
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.
What converts digital signals to analog signals and vice versa?
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
What similarities between analog and digital signals?
ANALOG:continuous,rate of transmission is slow,less reliable 2 transmit,more noise,interference is more DIGITAL:non continuous,rate of transmission is fast,more reliable 2 transmit,less noise,interference is less
What types of signals are used to transmit data on a wireless network?
none no1 lks u
What is calling function?
A device which carries out the two important tasks of modulating and demodulating the analog signals is called a modem. The analog signals encode the digital information at the time of modulation and decodes it back during demodulation to transmit the data.
A device to place digital signals on an analog system and vice-versa?
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
