Convolution, a Rare card
In mathematics, convolution is a mathematical operation on two functions f and g that produces a third function f ∗ g, as the integral of the product of the two functions after one is reflected about the y-axis and shifted.

Convolution quiz: 3 questions
Three questions on the Convolution card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The ______ is evaluated for all values of shift, producing the convolution function.
Answer
integral. The integral is evaluated for all values of shift, producing the convolution function. From the Convolution article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Morphine. Morphine 90 · List of mayors of New York City 83 · Convolution 80 · Ohm's law 76 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
List of mayors of New York City. List of mayors of New York City 700,000 · Morphine 400,000 · Convolution 320,000 · Gustave Eiffel 230,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- The term convolution refers to both the resulting function and to the process of computing it.
- The integral is evaluated for all values of shift, producing the convolution function.
- The choice of which function is reflected and shifted before the integral does not change the integral result.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Convolution article was read about 320,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 70: each hit it takes is cut by 28 %.
How to get Convolution
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
