A. High pass analog filter to low pass digital filter
B. High pass analog filter to high pass digital filter
C. Low pass analog filter to low pass digital filter
D. None of the mentioned
Answer:A
Which of the following filter transformation is not possible?
A. High pass analog filter to low pass digital filter B. High pass analog filter to high pass digital filter C. Low pass analog filter to low pass digital filter D. None of the mentioned
Explanation: We know that only low pass and band pass filters with low resonant frequencies in the digital can be designed. So, it is not possible to transform a high pass analog filter into corresponding high pass digital filter.
