Concept

A discrete, low-pass IIR filter that smooths time-series data by assigning exponentially decreasing weights to past observations using the formula s_t = αx_t + (1−α)s_{t-1}.

Um filtro discreto passa-baixa IIR que suaviza dados de série temporal atribuindo pesos exponencialmente decrescentes às observações passadas usando a fórmula s_t = αx_t + (1−α)s_{t-1}.
