摘要：One apparatus includes a notch filter that has a state obrver unit and a parameter adaptation unit. The state obrver unit is configured to receive a sampled noisy electrical signal and a sampled filtered electrical signal, the state obrver unit having an estimated noi signal output, the estimated noi signal output carrying an

estimated noi signal to be subtracted from the sampled noisy electrical signal, resulting in the filtered electrical signal. The parameter adaptation unit is configured to receive the estimated noi signal and an error signal from the state obrver unit. The parameter adaptation unit is also configured to determine, bad on the estimated noi signal and the error signal, an updated estimated noi frequency, thereby causing the state obrver unit to generate an updated estimated noi signal to be provided on the estimated noi signal output.
