An analog signal is a signal of varying amplitude.
The signal can be:
Light of different intensity
Light of different colour
Varying voltage like that produced by an MP3 player or Computer Soundboard.
Varying levels of radiation
We can easily compare the Analog signal with waves on the ocean. They go up and down and can vary in speed, size and intensity.
Digital signals are very different.
Digital signals are either on or off.
In light, we either have light on, or we do not have light.
Analog measuring is often a part of describing when a digital signal is a zero or a one.
We measure for levels of light, or levels of voltage to define whether the signal is supposed to be interpreted as a zero or a one.
This makes digital signals very resistant to background noise and they can travel very far with little or no degradation.
Digital signals are very suitable for transferring information. This is actually what they are all about.
Analog and digital signals go these days hand in hand when it comes to music.
We transform an analog signal into its digital representation and by recording the digital information we do not get loss of information.

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.
Why is there less interference with digital signals than analog signals?
Analog signals require higher fidelity than digital signals because digital are either on or off while analog are continuous. A small difference in an analog signal is not detectable while it requires a large difference to turn on into off (digital signal). Error correction is easier with digital signals.
How are digital signals in radio broadcast converted to analog signals inside digital transmission equipment before sending the signals to the antenna for transmission?
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
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 aerials different from analog ones?
Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.
What is the transfer of digital or analog data using digital or analog signals?
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
What is needed to convert digital signals to analog signals?
DAC
Is triangular wave is analog or digital?
It's usually analog, but digital signals can be converted, if needed.
Which piece of network hardware converts analog signals to digital and digital signals to analog?
a modem
What is digital analog simulators?
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.
