what are the DIFFERENCES between analog and digital signals?
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?
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
analog technology examples
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.
