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

Analog vs. Digital

Digital is better than analog because digital is more modern than analog. also digital has better quality. Lastly it is easier to use.
