Flowcharts of the newly proposed algorithm. (a) Flowchart of the two-sided filtration technique; (b) Flowchart of the multi-iterative approximation technique. Y _out [n] = Fi|_H(z) <X_in[n]>indicates that the input X_in[n] is filtered by the system H(z), and the relevant output is Y _out [n]. yⁿ_me[n] = BSFT (x _me [n], f_s, f₀, Δf) indicates that the input x _me [n] is processed by the Two-sided filtration technique with the specified parameters f_s, f₀ and Δf, and the relevant output is yⁿ_me[n].
