| Сводка≠ | The Wiener filter is an optimal linear filter that minimizes mean-square error between the desired signal and the filter output given knowledge of signal and noise statistics. Developed by Norbert Wiener in 1949, it provides the theoretical foundation for optimal filtering and remains the benchmark against which all other linear filtering methods are compared. | Infinite Impulse Response (IIR) filters are recursive digital filters that use feedback to achieve sharp frequency response characteristics with minimal filter order. Unlike FIR filters which depend only on past inputs, IIR filters also use past output values, allowing them to achieve steep rolloff with fewer coefficients. However, this feedback structure requires careful stability analysis. |
