摘要
An off-line modeling system (50) is provided for modeling a feedback path and a secondary path by calculating feedback neutralization filter taps and secondary path compensation filter taps. The off-line modeling system (50) includes a reference sensor (16), a secondary source (18), an error sensor (20), and an off-line modeling circuitry (10). The reference sensor (16) receives a noise signal and a feedback signal (22) and generates a primary signal x(n) in response. The secondary source (18) receives a modeling signal v(n) and provides the modeling signal v(n) to the feedback path and the secondary path. The error sensor (20) receives a residual signal generates an error signal e(n). The off-line modeling circuitry (10) receives the primary signal x(n) and the error signal e(n) and generates the modeling signal v(n) while modeling the feedback path and the secondary path.
