• To duplicate data

• To remove unwanted components

• To add noise to data

Which of the following is a characteristic of a low-pass filter?

• Blocks low frequencies

• Amplifies all frequencies

• Allows high frequencies to pass

What type of filter would you use to eliminate high-frequency noise?

• Notch filter

• Band-pass filter

• High-pass filter

• Low-pass filter

Which filter is best suited for isolating a specific frequency range?

• All-pass filter

• Band-pass filter

• High-pass filter

• Low-pass filter

In advanced filtering, what is a common technique used to handle complex data sets?

• Data duplication

• Simple averaging

• Fourier transform
