Explanation: At audio frequencies, inductor becomes problematic, as the inductors become large, heavy and expensive. 4. The problem of passive filters is overcome by using
A. Analog filter
B. Active filter
C. LC filter
D. A combination of analog and digital filters
Answer:A
Explanation: At audio frequencies, inductor becomes problematic, as the inductors become large, heavy and expensive. 4. The problem of passive filters is overcome by using
A. Analog filter B. Active filter C. LC filter D. A combination of analog and digital filters
Explanation: The active filters enclose as a capacitor in the feedback loop and avoid using inductors, this way inductorless active filter are obtained. 5. What happens if inductors are used in low frequency applications?
