PROBLEM TO BE SOLVED: To provide an information processing device capable of applying filter processing to an arbitrary signal position with a small memory use amount.SOLUTION: An information processing device 100 for applying a linear filter to a signal includes a vector calculation part 12 for using a first vector given as an initial value, and calculating the n-th vector by adding the n-th signal value to the product of the n-1-th (n is an integer of two or more) vector and a matrix, and an output value calculation part 14 for outputting a difference obtained by subtracting the product of one vector and the powers of the matrix from the product of the other vector and the powers of the matrix between two vectors extracted from n vectors calculated by the vector calculation part as an output value of a linear filter.SELECTED DRAWING: Figure 4 |
