Abstract

"CIRCUITO EM ANEL TRAVADO EM FASE". é apresentado um detector de fase que á ativado com ambos os flancos ascendente e decadente de um sinal de pulso de entrada. Isto efetivamente duplica a freq³ência do sinal de entrada. Quando o detector de fase é usado em um circuito travado em fase, a freq³ência duplicada significa que relação de divisão mais baixo pode ser usada, reduzindo dessa maneira qualquer contribuição de ruído desse modo introduzida.
