Abstract

"PROCESSO, APARELHO E SISTEMA PARA DIGITALIZAR A FASE DE UM SINAL DE ENTRADA" Um digitalizador de fase e processo com compensação de erro é fornecido e utiliza gravações de uma referência de fase gerada digitalmente para medir o tempo relativo entre eventos, tais como, por exemplo, entre o cruzamento zero de entrada e os pulso de amostra. A referência digital possui uma freq³ência constante que é igual à freq³ência de sinal desejada, e dessa forma a fase de referência pode ser utilizada para medir o tempo entre os eventos. Consequentemente, pela utilização da referência de fase gerada digitalmente existente, os "custos" com hardware associados com a implementação das tentativas de compensação de erro do digitalizador de fase anteriores podem ser significativamente reduzidas e/ou eliminadas.
