ベッセルフィルタ
1. Bessel filterIn electronics and signal processing, a Bessel filter is a type of linear filter with a maximally flat group delay. Bessel filters are often used in audio crossover systems. Analog Bessel filters are characterized by almost constant group delay across the entire passband, thus preserving the wave shape of filtered signals in the passband. The filter's name is a reference to Friedrich Bessel, a German mathematician (1784–1846), who developed the mathematical theory on which the filter is based.
