what is the diffrence between analog and digital?

Answer 1

you mean like clocks?
analog is the one with the hands (like on your wall)
digital is the one with the numbers only (like in your car)

Hope that helps!

Answer 2

The key difference between analog and digital technologies is that analog technologies record waveforms as they are, while digital technologies convert analog waveforms into sets of numbers, recording the numbers instead. When played back, the numbers are converted into a voltage stream that approximates the original analog wave. Both analog and digital test equipments and devices can be acquire through rental service at techrentals.

Answer 3

In communications, analog means one continuous signal. Try to imagine one continuous wavy line. That is a visual representation of analog. Also, old vinyl records were recorded and played using an analog signal.

Digital means that the signal cycles through discrete states of on and off. The signal goes through these cycles so fast, you can't detect the change without special equipment. Music in CD and MP3 form is an example of a digital signal.

Answer 4

Analog is a direct transfer of signal and tends to be a more mechanical method. For example, analog tape recording converts the analog wave signal from the microphone directly to a tape, and the tape is later read and amplified.

Digital is a CONVERSION of a signal into something else, usually a pattern of numbers. For example, taking a sound wave and converting digitally will "translate" the wave into numbers that are saved as data. The data is later read and sampled or translated back into a wave form that is amplified.

Answer 5

Analogue gives a continuous variable signal whereas digital gives a numerical value

Answer 6

a variable signal continuous in both time and amplitude that is analog

digital is where it is converted into binary or numeric
