Abstract

método e disposição para determinar frequência. trata-se de um método para determinar uma frequência de um sinal de entrada (in), um primeiro valor de contagem (n1) é determinado ao contar as bordas de relógio de um sinal de relógio de referência (clk) enquanto o sinal de entrada (in) corresponde a um primeiro valor de nível (l1). ademais, um segundo valor de contagem (n2) é determinado ao contar as bordas de relógio do sinal de relógio de referência (clk) enquanto o sinal de entrada (in) corresponde a um segundo valor de nível (l2). a frequência do sinal de entrada (in) é determinada como uma função do primeiro e do segundo valores de contagem (n1, n2).
