What is a oscilloscope use for?
It is a type of electronic test instrument that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis).

What is the difference between analog and digital communications?
Analog means continuous transmission of data whereas digital means discrete transmission of data. In analog communications we are transmitting finite amount of data in infinite amount of information. so,there is a possibility of occurrence of noise. where as in digital we are transmitting finite amount of data in finite amount of information. so , out of these two, digital is most efficient.
What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
What do you mean by interference and noise in electronics signals and systems?
One person's interference is another person's signal ... literally. For example, in ordinary AM radio, signals on the same frequency as a local station, but coming from another city some distance away, may cause background sounds that make listening to the station difficult or unpleasant. In other cases, transmitters emit 'harmonics' of their intended radio signal, which overlay carriers on other frequencies producing a similar effect. There are many other causes and sources of interference. Noise is another matter however, although it also 'interferes' with the operation of systems. Ordinarily, noise is no one else's signal, that is, it does not carry any information. Sources of noise include automobile ignition systems, electric motors, and the Sun, among many other things. The result is the same as far as the signal of interest is concerned however - both noise and interference cause problems receiving the desired signal properly, whether by causing objectionable sounds in the background of a radio program, 'snow' on a (non-digital) TV display, or errors in digital reception or data transmission (which can cause the complete loss of a digital TV signal for example). Noise and interference are also problems in systems where there is no intent to transmit or receive a radio carrier. For example, in computer systems, traces on circuit boards or in cables move data from one place to another in order to carry out the functions of the system. When traces are placed next to each other over (relatively) long distances on the circuit board or in a cable, the impulses can couple into the adjacent traces causing errors in the data transferred, such as corruption of data files or malfunctions of programs. In this example, the source of the problem is technically 'interference', but noise can also occur within systems, for example from a defective power supply or a poor contact in a connector. Many techniques are widely used to avoid the problems of noise and interference, including shielding, twisted pair wiring, FM and PM modulation, and forward error correction (FEC) among others. --- Very lengthy explanation of something very simple, NOISE INTERFERENCE is really unwanted signals introduced by noisy parts. Interference, however, may come from radio, tv, magnetics, and many other sources, including blocking of the signals. --- (See discussion)
What are the disadvantages of a digital multimeter?
An analog meter will respond to linearly as current is present . digital meters cannot do that not until the conversion is complete. in essence an analog meter is human friendly as compared to a digital meter. both have their places in applications.
What is digitization on digital library?
Digitization, usually means to take an analogue source material and save it in digital form, for storage and retrieval by computers and other digital equipment.
Why are floppy disks used for temporary storage?
Data can be easily loss when floppy disc is placed near a source of magnet or radio wave interference.
How do you set the input voltage of cathode ray oscilloscope?
first we connect the oscilloscope with the function generator or whatever the source of the input voltage , there will be a wave ,we try to adjust its amplitude using oscilloscope ..and this amplitude will be the peak to peak voltage..putting into consideration how volt/ div while measuring the amplitude
What is the part of the computer where you can save information to a disk?
Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. (Source: wikipedia)
Which instrument is best to use to check whether the source of supply is AC or DC?
The simplest is a voltmeter; the best is an oscilloscope. All modern voltmeters have an AC/DC selector switch. When set to AC and measuring a DC source, the reading will be 0; when set to DC and measuring an AC source, the reading will be 0 or varying wildly. An oscilloscope will show you a flat line for a DC source, and a sinusoidal curve centered at 0 for an AC source.
What are digital codes that can be used to authenticate the source of files?
Digital Signatures.
What do cell use as a source of energy and for source of energy storage?
Carbohydrates
Digital license is an electronic attachment?
its source
What is the biggest source of error for standard GPS?
Interference of signals with buildings or other structures.
What do you use as a source of energy and for energy storage?
protiens
What is the static interference on your phone line it sounds electrical?
Probably localised interference from a nearby source. Many electrical motors don't have suppressors fitted - when they run, they send out interference which can be picked up by any radio or telephone.
Is there a software for digital asset management?
An open source digital asset management software program is used to manage decisions and tasks that surround the ingestion, cataloguing, storage, retrieval, and distribution of digital assets.
