What One Need to Know About Electronic Counters and Digital Timers


  1. A counter is a device in computing and digital logic that isused to store and display the particular event so many times. An electroniccounter is a type of device that is used for several functions. Normally anelectronic counter is used for counting the number of pulses coming at theinput line in a specified time period.
  2. Electronic counters are single or multi-function unit that can be used to specify the time or rate. Some of the electronic counters are pre programmed and are used to perform more than one function. Single function electronic counters are either single directional or bidirectional. These counters are described by its specifications like durable, rugged, compact design and easy to use. The counters must possess memory since it has to remember its past states. With other sequential logic circuits counters can be synchronous or a synchronous. The applications of the counters mainly involve in digital clock sand in multiplexing.
  3. Electronic counters can be implemented by using register type circuits like flip-flops. They are classified into different types such as:
    Synchronous counter
    Asynchronous Counter or Ripple Counter
    Decade Counter
    Ring counter
    Cascaded counter
    Johnson counter
    Modulus counter
  4. Digital Timers
    Digital timers keep track of timing. Some products are programmable while others may be fixed at a set internal time and function. In addition to the number and type of functions, these devices differ in terms of time range settings.
    If one remembers, a few years ago microwave ovens use tohave a mechanical timer which allowed cooking things for a limited amount oftime. However, the newer microwave ovens now feature electronic digital timers.These old fashioned mechanical devices are today giving way to the modernelectronic ones, and for good reasons.
  5. Benefits of using digital timers over mechanical timers
    The main important benefit of an electronic timer is the cost. Electronic digital timers are very much cheaper to manufacture compared to those products that have springs and clockwork parts. Businesses and manufacturing companies that manufacture appliances have fierce competition, and cutting costs is an excellent way to stay ahead of competitors.
    Efficiency is another major important advantage of electronics. Mechanical clock systems can slowly wear over time, and lose their efficiency. Many of these mechanical devices also have daily clocks, and it is very important for them to keep proper time. Electronic products like digital timers are more accurate than those mechanical ones, and accuracy is vital for some products.
    Electronic timers have very little things to wear out when compared with mechanical timers, which is also an important thing to consider. The clock mechanism is subject to friction, and this does not happen within the electronic timer.
    Many electronic timing products can be user customized. For example, one can set alarm clock to any time of the day or night that they want. Old fashioned alarm clocks cannot distinguish between AM and PM, whereas, in digital timers it is easier to set an alarm and forget about it. Ones the alarm goes off, one can reset it for the next day.
