Abstract :
The well-known broadband active noise control (BANC) system using an FIR filter usually works well when the primary and reference noise signals are periodic in nature. This paper investigates the mean convergence of weight errors of the BANC system in the presence of multiple harmonic excitation. Difference equations governing the mean convergence of the system are derived and discussed in detail. The obtained analytical results enrich our understanding of the BANC operated in an environment with multiple sinusoids. Extensive simulations are conducted to support the analytical findings.
