what are the DIFFERENCES between analog and digital signals?

Analog signals are continuous signals represented by sine waves with an infinite range of values. The values are more exact but are difficult to work with.

Digital signals are discrete signals represented by square waves with a finite range of values. The values are not as exact but easier to work with.

what is analog and digital technonology?

Analog technology: a wave with an electrical current that is recorded or used in its original form. The vibrating electromagnetic creates an electric current that is used to produce sound to produce sound


Digital technology: the information is then converted into numbers or digits that are stored in the digital device. In the digital recording, the amplitude of the sound wave is sampled many times per second.

digital technology examples

These are examples of digital technology because they are made up of electricity and wires. examples like these were mostly used during the 21st century.

analog technology examples

These are examples of analog technology because they are made up of gears and sometimes electricity. Examples like these were mostly used before the 21st century.
