Adaptive notch filters from lossless bounded real all-pass functions for frequency tracking and line enhancing

The authors introduce constrained adaptive notch filters which are synthesized from a numerically robust all-pass filter section. This section is realized as a structurally lossless bounded real function which is canonic in both multipliers and delay elements. The notch filter structures admit ortho...
