Which of the following is the input component in a Band Pass filter? A- Resistor B- Capacitor C- Inductor D Both a and b LO

To determine the input component in a Band Pass filter, let's analyze the options given:

Analysis of Options

1. Resistor: In a Band Pass filter, resistors can be used to set the gain and affect the filter's response.
2. Capacitor: Capacitors are crucial in forming the frequency response of filters, especially in high-pass and low-pass configurations.
3. Inductor: Inductors are also integral in controlling the reactive components of the filter, particularly in low-pass and high-pass behaviors.
4. Both A and B: This suggests that both the resistor and capacitor together could serve as input components.

Conclusion

A Band Pass filter typically combines resistors, capacitors, and inductors to allow signals within a certain frequency range to pass while attenuating frequencies outside that range. However, the essential components primarily involve resistors and capacitors for the input.

Final Answer

D: Both A and B is the correct choice as both the resistor and capacitor can function as input components in a Band Pass filter.
