Digital Clocks vs. Analog Clocks

Taylor Nigemann and Gavin Jernigan

Why digital is better than analog

Digital is better than analog, as shown in clocks for many reasons including: easier to read, and accuracy of time. One reason for a digital clock to be better than an analog is how you can read the time. With a digital the time is represented in digits making the time easier to be read then that of the hands on an analog clock. Another reason for digital being better is the accuracy of the time, on a digital clock it is more accurate times, on an analog clock the minutes can be off, and when daylight saving times comes you can reset a digital clock easier than an analog. Another reason is analog clocks loose time faster then a digital clock.

Examples of Analog Clocks

Who, when, what, where and why

  1. Who Uses This: Everybody who reads time.
  2. When Is It Used: The clock is used whenever somebody needs to know what time it is.
  3. What Is It Used For: The clock is used to read time and to calculate speed.
  4. Where Is It Used: The clock is used around the globe.
  5. Why Is It Used: To read time.

Examples of Digital Clocks

How it works?

Analog

An analog clock or quartz is an oscillating clock that also has a 12 hour indicator on the face, which is the numbers that are seen and what both hands point to on the clock. The time is shown by an hour hand (shorter) and a minute hand (longer) which are powered by gears under the face of the clock. The main source of power in an analog clock is the direct electrical currents or a battery. This power supplies the controller mechanism that is an important power support to the oscillator. The controller also makes the wheel chain move which is responsible for the movement of the minute and hour hand, is also the cause of the ticking noise a clock makes.

Digital

A digital clock works by displaying time in a "7- segment display", light is shown through certain segments out of 7. In the clock there is an oscillator, when an electric charge goes through the crystal it causes a small sound. The sound made is changed into a electronic signal much like devices used for communicating. The electronic sound wave gets reduced from a 60 Hertz oscillation to a 1 Hertz oscillation by a series of counters, each 1 Hertz is 1 second. Each counter count for a different amount of oscillations, and each counter is hooked up to a chip to display the right number in the "7- segment display".

What is an Oscillator

A piece in side of every type of clock, that is a crystal made out of glass.
