| Sumario: | This work describes an active noise control system implementation with reduced, low cost hardware using the EDU-CIAA-NXP board. The filtered-X LMS algorithm is described in its feedforward and feedback configurations, and design details for anti-alias and reconstruction filters are given. The software driving the system is described and test results in feedforward configuration are shown. Using a pure tone as the perturbing signal, a 30dB attenuation was achieved, which is adequate according to performance requirements in active noise control applications. |
