May aid interference suppression in measurements; leaves open broader validation before adoption.
A new pole-radius-varying IIR notch filter algorithm significantly reduces transient effects when eliminating sinusoidal interference compared to traditional filters.
Tan et al. (2012) studied this question. Pole-radius-varying IIR notch filter vs. Traditional IIR notch filter was evaluated on Transient effect reduction when eliminating a sinusoidal interference. The developed pole-radius-varying IIR notch filter significantly outperformed the traditional IIR notch filter in reducing transient effects during sinusoidal interference elimination.
