The Adaptive IIR notch filter has been widely used in many signal processing applications, especially in the estimation of the sinusoid component with unknown frequency buried in noise.
自适应IIR陷波器在许多不同的信号处理场合,尤其在估计淹没在噪声中的正弦波频率方面得到广泛应用。
Two examples that are IIR notch filter and IIR low-pass filter are given, the stability of filters and the effects of quantification of coefficient are also analyzed.
