WebMar 1, 2008 · Adaptive IIR notch filter (ANF) is well known as a tool to detect, eliminate, or enhance a narrow band or noisy sinusoidal signals with unknown amplitude, phase, and frequency. It has been widely employed in many applications such as in biomedical engineering, control engineering, radar, sonar, communication systems, and so on. WebAbstract: A novel lattice-based adaptive infinite impulse response (IIR) notch filter is developed which features independent tuning of the notch frequency and attenuation bandwidth. The internal structure is based on planar rotators, ensuring reliable numerical behaviour and high processing rates in CORDIC environments. photo editor to make you look thinner https://thehuggins.net
