Analog vs. Digital
Analog and Digital technology by: Emma Campbell
3 examples of analog technology
1. Record player-circles going around the disc {waves}. When the needle touches the disc it allows music.
2. Clock-the clock works on frequency, when the hour hand passes the 12 the clock/gears switch.
3. Analog phone-you speak on one end and listen on the other. Sound waves travel to the other end.
3 examples of digital technology
1. I Phone-They read the numbers in patterns to make the phone work and show on the screen.
2. CD-there are land {the spaces} and pits {holes} in the discs that are only visible in a really magnified microscope.
3. Computer-reads the signals from the CD's and it turns into a wave. The wave is sent to the speakers so we can hear the music.
3 differences of analog signals
1. The waves in analog signals are round and bumpy while the digital signals are pointy and square.
2. Analog signals are infinite/continuous and digital signals are discrete/finite
3. Digital uses numbers 1 and 0 analog does not.
3 differences between analog and digital technology
1. Analog is clearer {better outcome}
2. Analog is harder to use
3. Analog is lower cost and digital is higher cost
