Question:
What are the advantages of using active filters over passive ones?
Answer:
Active filters offer several advantages over passive filters:
- Adjustability, allowing precise tuning of parameters like the cutoff frequency.
- Providing gain along with filtering, unlike passive filters.
- High input and low output impedance, minimizing signal loss.
- Stability, especially at high frequencies, due to built-in feedback mechanisms.
- Can operate over a wide range of frequencies with minimal changes
