Introduction A/D Conversion Error -generated by the filter input quantization process If the input sequence xn has been obtained by sampling an analog signal a(t, then the actual input to the digital filter is xn=rinteln where en is the a/d conversion errorIntroduction • A/D Conversion Error - generated by the filter input quantization process • If the input sequence x[n] has been obtained by sampling an analog signal xa (t), then the actual input to the digital filter is x[n] = x[n]+ e[n] ^ where e[n] is the A/D conversion error
