Neste artigo, propomos um novo filtro notch de resposta ao impulso infinito adaptativo de segunda ordem (IIR) baseado em rede que usa um algoritmo de adaptação simplificado. A análise do estado estacionário da estrutura proposta é então estudada com base na análise do erro quadrático médio das flutuações dos coeficientes variáveis do estado estacionário. A análise é usada para derivar expressões analíticas simples para a variância do coeficiente da variável em estado estacionário e um limite superior para a constante de adaptação do tamanho do passo. Os resultados mostram-se úteis no projeto de um demodulador FSK utilizando a estrutura proposta. Os resultados da simulação computacional são mostrados para confirmar as expressões analíticas derivadas.

Abstract: In this paper we propose a new lattice based second-order adaptive infinite impulse response (IIR) notch filter that uses a simplified adaptation algorithm. Steady-state analysis of the proposed structure is then studied based on the mean-squared error analysis of the steady-state variable coefficient fluctuations. The analysis is used to derive simple analytical expressions for steady-state variable coefficient variance and an upper bound for the step size adaptation constant. The results are shown to be useful in designing an FSK demodulator using the proposed structure. Computer simulation results are shown to confirm derived analytical expressions.
