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.
morse code
Morse code is a combination of short taps (dots) and long taps (dashes) represent numbers and letters.
digtial clock
The digital clock is which the hours, minutes, and sometimes seconds are indicated by digits rather than by hand on a dial.
cd
A cd stores Digital signals in a thin layer of aluminum. The aluminum layer has a series of pits. Each pit is a 0, and each non-pitted religion called land, is a 1.
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.
record player
The analog signal is carved into a plastic disk. The needle or the stylus creates vibrations in an electromagnet. The vibrating electromagnet creates a current used to produce sound.
the human voice
the human voice is apart analog technology because the sound waves are continuous.
