What is a asynchronous decade counters?
Difference between synchronous and asynchronous counters?
Synchronous counters are the ones in which each flip flop is driven by the same clock. whereas in asynchronous counters, each flip flop is driven by different clock. output of the preceding flip flop is used as as a clock for the next flip flop. Synchronous counters can do any sort of counting like even count, odd count, to skip a number etc, but asynchronous counters can do only up or down counting. This is the reason why the design of asynchronous counters is simpler than that of synchronous counters.

What are differences between asynchronous counter and synchronous counter?
Synchronous Counters Synchronous counters typically consist of a memory element, which is implemented using flip-flops, and a combinational element, which is traditionally implemented using logic gates. Logic gates are logic circuits with one or more input terminals and one output terminal, in which the output is switched between two voltage levels determined by a combination of input signals. The use of logic gates for combinational logic typically reduces the cost of components for counter circuits to an absolute minimum, so it remains a popular approach. Clock Pulse Synchronous counters have an internal clock, whereas asynchronous counters do not. As a result, all the flip-flops in a synchronous counter are driven simultaneously by a single, common clock pulse. In an asynchronous counter, the first flip-flop is driven by a pulse from an external clock and each successive flip-flop is driven by the output of the preceding flip-flop in the sequence. This is the essential difference between synchronous and asynchronous counters. Asynchronous Counters Asynchronous counters, also known as ripple counters, are the simpler type, requiring fewer components and less circuitry than synchronous counters. Asynchronous counters are easier to construct than their synchronous counterparts, but the absence of an internal clock also introduces several major disadvantages. The flip-flops in an asynchronous counter change states at different times, so the delays in changing from one state to another -- known as propagation delays -- add up to create an overall delay. The more flip-flops an asynchronous counter contains, the greater the overall delay. Considerations Typically, asynchronous counters are less useful than synchronous counters in complex, high-frequency systems. Some integrated circuits react faster than others, so if an external event occurs close to a transition between states -- when some, but not all, the integrated circuits have changed state -- it may introduce errors into the counter. Such errors are difficult to predict because of the randomly variable time difference between events. Furthermore, propagation delays can make it difficult to detect, or decode, the output state of an asynchronous counter circuit electronically.

What is does the term asynchronous mean in relation to counter?
Counter circuits made from cascaded J-K flip-flops where each clock input receives its pulses from the output of the previous flip-flop invariably exhibit a ripple effect, where false output counts are generated between some steps of the count sequence. These types of counter circuits are called asynchronous counters, or ripple counters.

How many blue counters must be added so that the ratio of yellow counters to total counters is 1 to 6?
Let the number of Yellow counters you already have is Y Let the number of non-yellow counters you already have is Z Then the current ratio of Yellow counters to the total counters is Y : Y + Z Let the number of Blue counters you add be B After they have been added, the ratio of Yellow counters to the total counters is Y : Y + Z + B This is 1 : 6 Thus Y = 1 and Y + Z + B = 6 → Z + B = 5 Which means that for the Yellow counters you have you will have five times as many counters made up of whatever non-Yellow counters you originally had plus the Blue counters you added. Thus to find out how many Blue counters to add, take the number of Yellow counters, multiply it by 5 and subtract the number of non yellow counters you originally had. examples: You had 6 Yellow counters Add 6 × 5 - 0 = 30 Blue counters Which gives you 6 Yellow and 30 Blue counters → ratio Yellow : total counters = 6 : 30 + 6 = 6 : 36 = 1 : 6 You had 4 Yellow counters and 6 Red counters Add 4 × 5 - 6 = 14 Blue counters Which gives you 4 Yellow counters, 6 Red counters and 14 Blue counters → ratio Yellow : total counters = 4 : 6 + 14 + 4 = 4 : 24 = 1 : 6 You had 4 Yellow Counters, 2 Blue counters and 3 Red counters Add 4 × 5 - (2 + 3) = 15 Blue counters Which gives you 4 Yellow counters, 3 Red counters and 2 + 15 = 17 Blue counters → ratio Yellow : total counters = 4 : 3 + 17 + 4 = 4 : 24 = 1 : 6

How many counters are needed to make a square array with 5 counters on one side?
If you're making an outline of a square, then 16 counters. You have the 4 corner counters, each shared by 2 sides and then in between the corner counters there are 3 counters on each of the 4 sides (4*3 = 12). If you're filling the inside of the square with counters, then you have 5 rows of 5 = 25 counters.

What are spell counters in Yu Gi Oh?
Spell counters are as treated like all counters: Counters. Though for an answer this short, it is difficult to really understand truly of counters. let us begin with a very interesting creature I like it call: The Venoms and Aliens. Aliens and Venoms each have their own unique forms of "counters." Aliens place alien counters while Venoms place Venom counters. So what are these counters and what do they do? First let us wipe away the spell, venom, alien, cloudian, all that confusing stuff and just go with "Counters." "Counters" are actually what ever it is that you can find to place on your card such as coins, dice, tape, little skittles, anything that can be used to know that it is a counter. I prefer to use dice, for you can set the dice to how many counters is on your current card. Basically it's like a number of some thing being put on your monster that will either accumulate or decrease. When a monster is removed from the field or flipped face down, the counters are removed. That being noted: The second thing to understand is that "Counters" are used for certain abilities depending on the counter it self. Venom counters tend to deduct attack points and kill off a creature. Remember though: Tend. But how do venoms work like that? Same as Spells and Alien counters.... Card effects on the field allow the counters to have a certain ability depending on the counters it self. Spell casters that uses Spell counters can remove these spell counters and usually only spell counters to preform certain effects or gain certain attack powers. Venom monsters abilities can use these counters to deduct attack points or even use spell cards that unleash a devastating effect that could destroy a monster when their attack hits 0 due to these counters. These counters how ever are for now render useless and are mainly just numbers or "things" being put on to cards that in time build up. The only time that counters are at use is when card effects on the fields like spell, traps, and monster effects are using these counters. That is when counters become devastating. In short, Spell counters are just like any counter but remain the most important golden rule of counters: Spell counters are not venom counters. Counters are counters, spell counters are spell counters, venom counters are venom counters, alien counters are alien counters and so on and so fourth. That being noted, I hope this helps you now understand, What are counters and spell counters.
