The Q, or quality factor, of a band-pass filter is defined as the ratio of the center frequency to the bandwidth. This describes how "selective" or "sharp" the filter is at its center frequency. Higher Q values indicate a narrower bandwidth relative to the center frequency, meaning the filter is more selective.
