What is the purpose of a low-pass filter?

To amplify all frequencies equally

To eliminate all frequencies except for the cutoff frequency

To allow high frequencies to pass through while attenuating low frequencies

To allow low frequencies to pass through while attenuating high frequencies

Correct Answer : To allow low frequencies to pass through while attenuating high frequencies

Explanation : A low-pass filter is designed to allow low-frequency components of a signal to pass through while attenuating high-frequency components. It effectively “filters out” the higher frequencies beyond the cutoff frequency, allowing only the lower frequencies to be present in the output signal.

Which type of passive filter is used to separate audio frequency bands in a speaker system

Low-pass filter

High-pass filter

Band-pass filter

Notch filter

Correct Answer : Band-pass filter

Explanation : A band-pass filter is employed to separate specific frequency bands from a complex signal. In speaker systems, band-pass filters are commonly used to separate audio frequency bands and direct them to the appropriate drivers, ensuring each driver receives the frequency range it is designed to reproduce.
