摘要：

We develop a canonical, adaptive cascade-structure IIR notch tilter to detect and track multiple time-varying frequencies in additive white Gaussian noise. The algorithm uses allpass frequency transformation filters and a truncated gradient, Simulations indicate that our algorithm is computationally simple, converges rapidly, and has good frequency resolution.
