What is the difference between transistor and transformer?
A transistor in the right circuit, contributes a POWER GAIN by taking energy from an external power supply. A transformer actually has losses but is primarily used for Impedance Matching. This is very useful in establishing the most efficient arrangements for transmitting power from the source to the load. Impedance matching is an important function of all power transfer systems.
Will cutler hammer breaker panel fit a GE breaker?
No, a Cutler Hammer will not work in a GE panel or vice versa.
What is the definition of AC-DC converter?
AC-DC converter such as a convertor by which we can convert alternative currents into direct current & its vice-versa. ...... anil allahabadi
How does white noise affect a signal?
It affects the signal due to the activity present in the electrons in the medium, when the temperature increases the electrons activity increases which increases the noise and vice versa
What is the function of the IC 7404?
It will give high output when the given input is low and also give LOW output when the given input is high (Vice versa).
How does a modum work?
A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.
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 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.
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 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.
What is A type of communications device that connects a communications channel to a sending or receiving device is a?
A type of communications device that connects a communications channel to a sending or receiving device is a modem. Modems modulate and demodulate signals for transmission over various types of media, such as telephone lines or cable systems. They enable digital devices to communicate with each other by converting digital data into analog signals and vice versa.
What are the advantages and disadvantages of an internal modem?
A modem is a device that converts analog signals to digital signals, and vice-versa. This would be required when you need to do that type of conversion (for example, over a phone line to transmit data).
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.
Where Dennis Hayes and dale discovered the modem?
Dennis Hayes and Dale Heatherington invented the modem in 1977 while they were at Stanford University. They developed the first commercially successful modem, which allowed computers to communicate over telephone lines by converting digital data into analog signals and vice versa. Their invention laid the foundation for modern internet connectivity, enabling a wide range of digital communication.
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.
