Analog systems are what we can call wave systems. they have a value that changes steadily over time and can have one of an infinite set of values in a range.

The term digital refers to the fact that the signal is limited to only a few possible values. in general, digit signals are represented by only voltages on a wire -0 volts ( which we called " binary o " or just "o" ) and 5 volts ( which we call " binary 1 " or just"1" ).

Analog signals include all natural signals and have continuous values. The use of analog signals has declined tremendously with the development of digital signals. Digital signals are more reliable due to encryption.

An analog communication system uses analog signals while a digital communication system uses digital signals. Often, like in the case of the landline telephone, these technologies complement each other.

analogue is pretty much manual and digital is electronic.

e.g. analogue clock is the one with the long hanles turning in 360 degrees, the second indicator moves 60 times per minute, the minute indicator moves 60 times per hour, and the hourly indicator and 24 hours in one day.

yes, useless information xD.

And the digital works with a battery that simply just show numbers. e.g. 3:35.

Analog systems are what I call wave systems. They have a value that changes steadily over time and can have any one of an infinite set of values in a range. Analog systems are what I call wave systems. They have a value that changes steadily over time and can have any one of an infinite set of values in a range example of analog system is transfer of audio wawe from microphone to speaker (audio amplifier).

Digital systems process digital signals which can take only a limited number of values (discrete steps), usually just two values are used: the positive supply voltage (+Vs) and zero volts (0V). digital systems having a 'square wave' appearance and example of a digital system would be the digital voice telephone system. The phone system uses something called Pulse Code Modulation(PCM). PCM uses 256 discrete voltage states to represent specific values or symbols. The phone system uses these discrete symbols to represent various values of sound on the phone line. Because there are only 256 symbols, the phone system can't reproduce the sound exactly, but it can sample the analog sound of the speaker's voice 8,000 times a second to create a 'close enough' approximation in digital format. Conversion from the analog to digital format is called quantization.

What is the difference between digital and analogs?

In chemistry, analog is a compound with a molecular structure closely similar to another. Analog is also relating to or using signals or info represented by a continuously variable physical quantity such as spatial position or voltage. Analog is often contrasted (opposite) of DIGITAL --like a clock showing the time represented by "hands" instead of being Displayed DIGITS.
