Learn about counters, devices that store and display the number of times a particular event or process has occurred. find out the difference between asynchronous and synchronous counters, decade counters, and some gate questions on counters. In this case (indeed in many cases in digital circuit design) this takes the form of more circuitry. since all flip flops are being clocked at the same time, rather than the clock rippling through, we need to add some logic to control when each flip flop toggles. below is a 4 bit synchronous counter. compare it to the 4 bit ripple counter above.
Learn how to design and build synchronous counters using j k flip flops, without ripple effects. explore synchronous up, down and up down counters, and their applications in machine motion control. Counters, consisting of a number of flip flops, count a stream of pulses applied to the counter’s ck input. the output is a binary value whose value is equal to the number of pulses received at the ck input. each output represents one bit of the output word, which, in 74 series counter ics is usually 4 bits long, and the size of the output. Counters calculate or note down the number that how many times an event occurred. counters are the crucial hard ware components, and are defined as “the digital circuit which is used to count the number of pulses”. counters are well known to us as “timers”. counter circuits are the best example for the flip flop applications. The 74ls90 integrated circuit is basically a mod 10 decade counter that produces a bcd output code. the 74ls90 consists of four master slave jk flip flops internally connected to provide a mod 2 (count to 2) counter and a mod 5 (count to 5) counter. the 74ls90 has one independent toggle jk flip flop driven by the clk a input and three toggle jk.

An up down counter is a combination of an up counter and a down counter. it can count in both directions, increasing as well as decreasing. depending on the type of clock inputs, counters are of two types: asynchronous counters and synchronous counters. we will take a look at all the types of counters and their circuits in detail below.
