Bessel filter

Encyclopedia : B : BE : BES : Bessel filter

Non standard name for "Linear analog electronic filter" template In electronics and signal processing, a Bessel filter is a variety of linear filter with a maximally flat group delay (linear phase response). 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.
