Types of Counters

Counters can be categorized into different types according to the way they are clocked. They are

Asynchronous Counters

Synchronous Counters

Asynchronous Decade Counters

Synchronous Decade Counters

Asynchronous Up-Down Counters

Synchronous Up-Down Counters

A counter is a digital sequential logic device that will go through a certain predefined states (for example counting up or down). Two main types of counters is Asynchronous and Synchronous counters.

Asynchronous Counter
-frequency operating is low
-cannot design random counters

Synchronous Counter
-frequency operating is higher
can design for sequence or random number

Types of counters

There are two types of counters available for digital circuits, they are

1. Synchronous counters

2. Asynchronous counter

Basic Digital Counter

Counter is an electronic circuit used to count the number of times an event occurs. In digital electronics counters are constructed using series of flip-flops. Although any flip-flop can be suitably connected to form a counter, most widely used are D and JK flip-flops

Counters have modes. The ‘mod’ of the counter represents the number of states of the cycles through it, before setting the counter to its initial state. For example, a binary mod 8 counter has 8 countable states. They are from 000 to 111. So the mod 8 counter counts from 0 to 7.

A binary mod 4 counter has 4 count states, from 000 to 011. So the mod 4 counter counts from 0 to 4. This means, in general a mod N counter can contain n number of flip flops, where 2n = N.

Counter is a sequential circuit. A digital circuit which is used for a counting pulses is known counter. Counter is the widest application of flip-flops. It is a group of flip-flops with a clock signal applied. Counters are of two types.

Asynchronous or ripple counters.

Synchronous counters.

a Counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal. Counters are used in digital electronics for counting purpose, they can count specific event happening in the circuit. For example, in UP counter a counter increases count for every rising edge of clock. Not only counting, a counter can follow the certain sequence based on our design like any random sequence 0,1,3,2… .They can also  be designed with the help of flip flops
Counters are broadly divided into two categories

1. Asynchronous counter

2. Synchronous counter

Asynchronous Counters

This type of counters have JK Flop-Flops arranged in a way that the output of one flip-flip feeds the clock of the following flip-flop [1] as shown in the figure below:

The asynchronous counter (also called the ripple counter) is relatively slow due to the fact that each flip-flop’s clock is dependent on the output of the previous flip-flop and because they have a non-zero propagation delay. The synchronous counter eliminates this issue as we will see in the next section [1].

A counter is a digital sequential logic device that will go through a certain predefined states (for example counting up or down) based on the application of the input pulses. They are utilized in almost all computers and digital electronics systems [1].

There are two main types of counters: Asynchronous and Synchronous counters.

Today we will learn about Counter. As usual, please get information about counter. You can search about up counter, down counter or counter randomly.
