Abstract
"MéTODO E CONVERSOR ANALóGICO-DIGITAL (ADC) PARACONVERTER UM SINAL DE ENTRADA ANALóGICO EM UMSINAL DE SAìDA DIGITAL". Um conversor analógico/digital(ADC) inclui um gerador de sinal de excitação configurado paraacrescentar um sinal de excitação analógico ao sinal de entradaanalógico do ADC antes da digitalização (isto é, quantização).Aamplitude do sinal de excitação é selecionada, com base nosníveis de potência de uma ou mais portadoras presentes na largurade faixa para a qual o ADC foi desenhado para operar. Oacréscimo do sinal de excitação ao sinal de entrada em domínioanalógico reduz o ruído de quantização tal como estímulos deconversão que resultam de não-linearidades na função detransferência do ADC.
