A filter bank is an arrangement of band-pass filters. A band-pass filter takes a signal as an input, and outputs only a specific frequency range, or "band," of that signal if it exists, while filtering out the other frequencies. As a result, a filter bank separates the original signal into several parts, each an isolated frequency range.
