Explanation: Filters are classified based on the design technique (analog or digital), elements used for construction (active or passive) and operating range (audio or radio frequency). 3. Why inductors are not preferred for audio frequency?
A. Large and heavy
B. High power dissipation
C. High input impedance
D. None of the mentioned
Answer:A
Explanation: Filters are classified based on the design technique (analog or digital), elements used for construction (active or passive) and operating range (audio or radio frequency). 3. Why inductors are not preferred for audio frequency?
A. Large and heavy B. High power dissipation C. High input impedance D. None of the mentioned
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
