Explanation: Typically active filters are more economical than passive filters. This is because of the variety of cheaper op-amp and the absence of inductor’s. 7. What are the most commonly used active filters?
A. All of the mentioned
B. Low pass and High pass filters
C. Band pass and Band reject filters
D. All-pass filters
Answer:A
Explanation: Typically active filters are more economical than passive filters. This is because of the variety of cheaper op-amp and the absence of inductor’s. 7. What are the most commonly used active filters?
A. All of the mentioned B. Low pass and High pass filters C. Band pass and Band reject filters D. All-pass filters
Explanation: All the mentioned filters use op-amp as active element and capacitors & resistors as passive elements. 8. Choose the op-amp that improves the filter performance.
