Abstract

INTERFACE VRS COM FUNÇÃO DE ARMAÇÃO 1/T. Um sistema de sensor de relutância variável (100, 400) para o processamento de um sinal de sensor de relutância variável (VRS, VRSS) incluindo um comparador de armação (108) e um circuito de armação (112, 412). O comparador de armação compara o sinal de sensor de relutância variável com um limiar de armação (ATH) que diminui proporcional a 1 / t desde um nível máximo predeterminado (ATH MAX) e afirma um sinal armado (ARM) quando o sinal de sensor de relutância variável atinge o limiar de armação. O limiar de armação pode ser diminuído com base em um fator de escalonamento multiplicado por 1 / t para garantir detecção de cada pulso do sinal de sensor de relutância variável. O limiar de armação pode diminuir para um nível mínimo predeterminado (MIN ATH) suficientemente baixo para intersectar o sinal de sensor de relutância variável e suficientemente elevado em relação a um nível de ruído esperado. O limiar de armação é resetado (RST) em resposta a um evento de temporização, tal como cruzamento de zero (ZD) do sinal de sensor de relutância variável. Figura 1 para acompanhar resumo.
