What converts digital signals to analog signals and vice versa?
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
A device to place digital signals on an analog system and vice-versa?
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
How does a modum work?
A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.
What is a transcode?
The conversion of analog video to a digital format, or vice-versa.
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...
How does a UART convert an analog signal to a digital signal?
A UART does not convert an analog signal into a digital signal. It converts a serial digital signal into a parallel digital signal, and vice versa. The letters UART stand for Universal Asynchronous Receiver Transmitter. It is, fundamentally, a pair of shift registers.
How is a modem facilitats communication different between computer?
a modem is a tool which can change analog sinal to digital signal and vice-versa. when the communication has to take place between the two computers then there is involvement of wires or some wireless technology. if communication exists between then it is through analog signals and computer can accept only digital signal. so,basically modem changes the analog signal to digital when the data is to be received at computer's end and hence it works and facilitates the commmunication between two or more computers.
How do you know if your TV is digital or analog?
"Standard-definition" (meaning 480i) Cathode-ray tube televisions are analog. CRT TV's are easily identifiable by their immense weight and the fact that their depth nearly matches their width and height. Newer, hi-def (720p, 1080i/p) televisions are almost all either lcd, plasma, or dlp, all of which are digital. for digital TV monitor shouldnot be of CRT.
What is modem?
The word itself is short for modulator-demodulator. A modem is a device that modulates (To vary the frequency, amplitude, phase, or other characteristic of electromagnetic waves) an analog signal to encode digital information. It also can take in an analog signal and decode the digital information from it (demodulates).In simpler terms, a modem is the box (usually provided by your internet Service Provider (ISP)) that tipically sits between the in the wall and either a wireless router or your computer.Its purpose is to translate the digital signals that your computer sends out into an electronic signal that can easily transmitted and decoded by another modem at the message's destination and vise versa.
What are the advantages of digital over analog?
The advantage of analog over digital or vice versa , is dependent on the input information type and / or signal amplitude where applicable , also on what the application is and other considerations like information / signal processing , storage , etc. The choice is decided by the advantages as per the requirements. As a rule the information carried by an analog signal is dependent on its instantaneous magnitude or position.Thus it is highly susecptible to corruption by extraneous noise sources which can affect the magnitude arbitrarily. On the other hand a digital signal typically carries information as changes in amplitude level between two ( or more ) arbitrarily predefined levels, arranged in a predetermined format and grouping ( more familiar as a code ). As long as the digital signal can be retrived without major loss in blocks of code , the original information can be mathematically retrived. Whenever the information and / or signal level is very small and / or in analog form , invariably some form of analog processing is required before any meaningful conversion to digital format or processing can be done. Now due to vast processing powers of digital circuits & computers , the advantage of analog is limited to very specialised requirements where the disadvantages of digital format would outweigh any other considertions. So for all purposes it would be invariably advantageous to use digital format and convert to analog whenever required. The only notable analog format which will always be required is for human sound & visual interface ( or for that matter other senses ) which the body perceives and processes only as analog signals , even the pseudo analog modes of Class D Audio Amplifiers , LCD Displays , Projection , Digital Printing etc. which operate in the Digital mode to simulate analog signal output. It may be noted that the Morse Code was essentially a digital format, while Semaphore ( uses Flag & Hand positions to convey information ) was an analog signal by virtue of hand position.
If both 7.1 analog out and HDMI out are connected from a Panasonic dmp-bd10a to the analog and HDMI inputs on an onkyo tx-sr875 how do you select one source to play over the other and vice versa?
Use the source select button on the remote. Answer: If you have an HDMI cable connected from your Blu-ray player to your receiver you don't need the 7.1 analog. The analog cables are inferior to the digital signal and HDMI can produce. The HDMI cable carries both an HD picture and HD digital sound (the best sound possible from a blu-ray.) If you remove the analog cables, choose the HDMI input and you will be fine.
What is the difference between baseband coaxial and broadband coaxial cable?
The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.
