 If formula_102 results from the inverse DFT of the product formula_103.formula_96 , then formula_102 will be the circular convolution of formula_85 and formula_84.If formula_46, formula_49..., formula_52 are chosen to be at least equal to the size of formula_83, then formula_112.This implementation technique is efficient with respect to computation, however it is prodigal with respect to storage as this method requires sufficient storage to contain all formula_46xformula_49x...xformula_52 points of the signal formula_84.
