Can you explain the different types of filtering in data analysis?
Sure! The main types of filtering include low-pass, high-pass, band-pass, and band-stop filters. Each serves a different purpose.
What does a low-pass filter do?
A low-pass filter allows signals with a frequency lower than a certain cutoff frequency to pass through while attenuating higher frequencies.
And what about a high-pass filter?
A high-pass filter does the opposite; it allows signals with a frequency higher than the cutoff frequency to pass and attenuates lower frequencies.
Can you give an example of where I might use a band-pass filter?
Certainly! Band-pass filters are often used in audio processing to isolate a specific range of frequencies, like a musical instrument's sound.
