    hi everyone, I'm doing a project in active noise control using kalman filter.

    I'm taking simulink-models as reference, which are demos> blocksets> signal processing> adaptive processing> acoustic noise cancellation (ANC), tracking filter (kalman). I need some guidance about how to implement the ANC using kalman filter.

    I tried a few configurations and replaced the normalized LMS filter with kalman in ANC. I connected "pilot's mic" to "In" and "ext. mic" to desired input d(n) (positive input in summer at Kalman's "out") and kept rest of the ANC circuit same. Now, when I run it, it gives an error
    "Check signal attributes. Input must be sample-based." why is it giving this error?

    Please give some suggestions on how to implement it.
