3 differences between analog and digital signals:


  • Analog signals are smooth.
  • Analog signals are continuous.
  • Analog signals have an infinite set of numbers (1,2,3,4,5,6,7,8,9,0).


  • Digital signals are square.
  • Digital signals are not continuous.
  • Digital signals are limited to the numbers 1 and 0 (Binary code).

3 differences between analog and digital technology:


  • Wave is recorded straight from the mic.
  • Can be amplified/sent through a speaker.
  • The sound is degraded (split up).


  • The analog wave is sampled.
  • Turned into numbers (1,0) that are stored on the digital device.
  • Sound does not degrade (split up) over time.

Why you should choose digital:

Digital pros:

  • Digital technology doesn't degrade (split up) noise.
  • Digital technology cost less than the high demand of analog technology.
  • Digital technology has a more processed, higher quality sound.

Analog cons:

  • Analog technology degrades (splits up) the noise.
  • Analog technology is on a higher demand and costs more than digital.
  • Analog has a staticky, broken up, lower quality sound.
