Convolution is a mathematical operator that generates the third function through function f and function g. Indicates the accumulation of F and G overlapping parts after flip and moving. If we regard a function that participates in Convolution as a range indicator function, convolution can also be seen as a promotion of "Moving Average. Its Applications include statistics, computer perspectives, image and signal processing, electrical engineering, and microequations. Convolution can be defined

1. The frequency of the individual 0 points correspondsA single 0 point corresponding to a fraction of 1-az-1,a can be a complex number. When z is in the value of the unit circle, we can write this fraction as 1-rejθe-jω to analyze.2. Multiple polesIf the system's H[n] is a real number, then the frequency response of the system must have a conjugate symmetric 0 points or poles (the system frequency response is a real coefficient polynomial). For example, assuming that the system function has a p

The probability of a bullet is a conditional probability, equal to the number of substrings 00 divided by 00 and 01 total (that is, the number of 0), the probability of the transfer of the bullet is equal to 0 of the ratio.The number of substring 00 is a,0 B, then two probabilities are A/b and b/n respectively, the problem is to compare a*n and b*b.#include Uva1636-headshot (discrete probability)

[Discrete logarithm] ultraviolet A 11916 Emoogle Grid Question: Apply K colors to an M * N matrix. There are B cells that cannot be colored, and each cell cannot be the same color as the cell above. If N and total result R are known, find the row M with the minimum satisfaction. All data has a modulo value of 100,000,007. Ideas: Because the X coordinates of the input vertex that cannot be colored must be within M. So record maxX. Divide the entire mat
