These counters find specialist applications similar to the decade counter (note: the 74x4017 decade counter is a Johnson counter), digital-to-analog conversion, etc. They can be implemented easily using D- or JK-type flip-flops.
Frequency counters designed for radio frequencies (RF) are also common and operate on the same principles as lower frequency counters. Often, they have more range before they overflow. For very high frequencies, many designs use a high-speed prescaler to bring the signal frequency down to a point where normal digital circuitry can operate. The ...
Most counters have four such rings, allowing the user to count up to 9999. A metal ring may be attached to aid in holding the counter, and usually half the ring is bent to allow it to fold flush with the counter when not in use. The counter is activated by pressing a button located above the screen. This causes the first ring to advance one number.
Number blocks, which can be used for counting. Counting is the process of determining the number of elements of a finite set of objects; that is, determining the size of a set. . The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or displacing) those elements to avoid visiting the ...

A web counter or hit counter is a publicly displayed running tally of the number of visits a webpage has received. Web counters are usually displayed as an inline digital image or in plain text. Image rendering of digits may use a variety of fonts and styles, with a classic design imitating the wheels of an odometer. Web counters were often ...

Using this principle, a counter can vary bet sizes in proportion to the advantage dictated by a count. This creates a "bet ramp" according to the principles of the Kelly criterion. A bet ramp is a betting plan with a specific bet size tied to each true count value in such a way that the player wagers proportionally to the player's advantage to ...
