What is the difference between analog and digital electronics?

Answer 1

digital works in binary , on/off, 1/0, +5 volts/ground.
analog is a voltage that varies between 2 extremes, and everywhere in between , like voltages to your speakers, or a voltage from a temperature sensor.

Answer 2

Analog electronics uses components that can have several states. They use transistors like regulators to have a lot of states. So you can control how much current passes through the transistors.

Digital electronics, relies on circuits that have switches (transistors used in only two states, like using a regulator in only two positions, off or max). You can either have the switch on, or off. And this is used to perform all the data processing.

We use digital electronics in general, since digital is a lot more tolerant to noise. Since there are only two states, there needs to be lot of disturbance before one state is mistaken for another. As a result, we can take more liberties while designing and go faster with digital electronics.

Analog has its own domains. The outside world is analog, so we use a lot of analog inputs and convert them to digital, process it and reconvert to analog output.

Hi. Digital is based on numbers, analog is based on responses.
