What are the differences between various types of filters?

There are several types of filters, including high-pass, low-pass, band-pass, and notch filters. Each serves a different purpose in signal processing.

Can you explain how a high-pass filter works?

A high-pass filter allows signals with a frequency higher than a certain cutoff frequency to pass through while attenuating lower frequencies.

What about low-pass filters? How do they differ?

Low-pass filters do the opposite; they allow signals with frequencies below a certain cutoff to pass while attenuating higher frequencies.

Are there practical applications for these filters?

Yes, high-pass filters are often used in audio processing to remove low-frequency noise, while low-pass filters can smooth out signals in data analysis.
