Analog data is a varying range of voltages based upon data coming from sensors, often based on real time events.
Digital data is represented by zeros and ones. One problem with digital data is the resolution of the data that can be represented. That is why 16-bit sound sounds better than 8-bit sound, and 24-bit sound has better quality than 16-bit sound. If you have 8-bits, then the data can only be representing in a range of 256 possibilities. However, 16-bits gives 65,536 different possibilities.

What does digital cable mean?
Digital signals permit greater transmission of data over analog signals. The URL http://telecom.hellodirect.com/docs/Tutorials/AnalogVsDigital.1.051501.asp has quite a bit of useful information on the differences between analog and digital broadcasting
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What is the basic difference between analog and digital system?
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
What is the difference between digital and analog signals in tabular form?
If we discuss the different between these two forms of the signals that is; analog and digital then we should discuss it in different aspects such as working, their architectures, pros and cons as well. The major differences among the two signals are listed below
How analog instrument interfaced with a digital instrument?
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
7 What term is used to describe the transformation of analog signals into digital signals?
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.
What converts digital signals to analog signals and vice versa?
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
What are the differences between analog system and digital system?
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.
A device to place digital signals on an analog system and vice-versa?
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
How are digital and analog signals similar?
They both convey differences in voltage level. An anologue signal can send any level between limits. A digital signal only sends two different levels, one represents a 1 or high level, the other represents 0 or low level.
