State Reduction
Any design process must consider the problem of minimizing the cost of the final circuit. The two most obvious cost reductions are reductions in the number of flip-flops and the…
State Diagrams and State Tables
Fundamental to the synthesis of sequential circuits is the concept of internal states. At the start of a design the total number of states required are determined. This is achieved…
MOD-4 Counter
Technically as well as being a 1-bit storage device, a single flip-flop on its own could be thought of as a MOD-2 counter, as it has a single output resulting…
MOD Counters
MOD Counters are cascaded counter circuits which count to a set modulus value before resetting The job of a counter is to count by advancing the contents of the counter…
Difference between Mealy machine and Moore machine
Mealy Machine – A mealy machine is defined as a machine in theory of computation whose output values are determined by both its current state and current inputs. In this machine…
Decade Counter
A decade counter counts ten different states and then reset to its initial states. A simple decade counter will count from 0 to 9 but we can also make the…
Synchronous Counter
Unlike the asynchronous counter, synchronous counter has one global clock which drives each flip flop so output changes in parallel. The one advantage of synchronous counter over asynchronous counter is,…
Asynchronous Counter
In asynchronous counter we don’t use universal clock, only first flip flop is driven by main clock and the clock input of rest of the following flip flop is driven…
Counters in Digital Logic
According to Wikipedia, in digital logic and computing, a Counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship…
What is the Difference Between Edge and Level Triggering
The main difference between edge and level triggering is that in edge triggering, the output of the sequential circuit changes during the high voltage period or low voltage period while, in level triggering,…
