Introduction A/D Conversion Error -generated by e the flter input quantization process If the input sequencexn has been obtained by sampling an analog signal (t), then the actual input to the digital filter is xn=xnl+eln where elni 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
