Article Title: A New Method for Active Cancellation of Engine Order Noise in a Passenger Car

Figure Lengend Snippet: Figure 11 shows the block diagram of the FxLMS-algorithm-based adaptive notch filter and the OW- FxLMS algorithm for the application of ANC to engine noise inside a vehicle. In the FxLMS -algorithm-based adaptive notch filter, two adaptive weights, wi1 (n) and wi2 (n), were used for each order. In the OW- FxLMS algorithm, the adaptive weight vector w(n) with different filter lengths was used for each order. The length of each weight vector was related to the total delay of the ANC system. The secondary path was considered for the application of ANC to engine noise.
