Where should analog to digital converter be placed?
where an analog signal is to be converted into digital signal,because in some applications we need digital signal where we have analog signal that is we use an A/D converter
How is digital audio decoded?
To have digital to audio played back it has to be changed back to analog with the use of a DAC or digital to analog converter. The DAC will take the digital signal and try to recreate it as a analog signal.
What are the differences between analog and digital transistors?
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
Difference between analog video and digital video?
analog video is generally a type of video form in which we have numerous waves in terms of crests and troughs in a continuous manner upside-down on X axis whereas, in digital video we have many bars that are upawrds and then downwards on X axis in a continuous manner that also includes two types of binary bits, either 0 or 1.
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
Audio Connectors?
Audio connectors and video connectors are electrical connectors for carrying audio signal and video signal, of either analog or digital format. Analog A/V connectors often use Shielded cable to inhibit radio frequency interference (RFI) and noise.
Different types of signal encoding technique?
n Digital data, digital signal n Equipment less complex and expensive than digital-to-analog modulation equipment n Analog data, digital signal n Permits use of modern digital transmission and switching equipment n Digital data, analog signal n Some transmission media will only propagate analog signals n E.g., optical fiber and unguided media n Analog data, analog signal n Analog data in electrical form can be transmitted easily and cheaply
Which circuit comes first analog or digital?
In terms of the history of the signal, it was the analog signal that came first. That doesn't mean that it can't still be used in conjunction with an analog signal in today's use.
Does a digital camera use digital signals?
The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing. The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing.
Compare digital services with analog services Give at least 5 points for each?
digital services with analog services we use binary digits 0 and 1 for digital serviceswe use electrical signal for analog service
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.
What is a video capture card?
Video capture card is a device, which is used to converting analog video signal to digital form
