Linkwitz–Riley filter (original) (raw)
Ein Linkwitz-Riley-Filter (L-R-Filter) ist ein elektronisches Filter, welches in Linkwitz-Riley-Frequenzweichen benutzt wird. Es ist nach seinen Erfindern Siegfried Linkwitz und benannt. Es ist auch als Doppeltes Butterworth-Filter bekannt, da es durch Kaskadierung zweier Butterworth-Filter gebildet wird.

| dbo:abstract | Ein Linkwitz-Riley-Filter (L-R-Filter) ist ein elektronisches Filter, welches in Linkwitz-Riley-Frequenzweichen benutzt wird. Es ist nach seinen Erfindern Siegfried Linkwitz und benannt. Es ist auch als Doppeltes Butterworth-Filter bekannt, da es durch Kaskadierung zweier Butterworth-Filter gebildet wird. (de) A Linkwitz–Riley (L-R) filter is an infinite impulse response filter used in Linkwitz–Riley audio crossovers, named after its inventors Siegfried Linkwitz and . This filter type was originally described in Active Crossover Networks for Noncoincident Drivers in the Journal of the Audio Engineering Society. It is also known as a Butterworth squared filter. A Linkwitz–Riley "L-R" crossover consists of a parallel combination of a low-pass and a high-pass L-R filter. The filters are usually designed by cascading two Butterworth filters, each of which has −3 dB gain at the cut-off frequency. The resulting Linkwitz–Riley filter has −6 dB gain at the cut-off frequency. This means that, upon summing the low-pass and high-pass outputs, the gain at the crossover frequency will be 0 dB, so the crossover behaves like an all-pass filter, having a flat amplitude response with a smoothly changing phase response. This is the biggest advantage of L-R crossovers compared to even-order Butterworth crossovers, whose summed output has a +3 dB peak around the crossover frequency. Since cascading two nth-order Butterworth filters will give a (2n)th-order Linkwitz–Riley filter, theoretically any (2n)th-order Linkwitz–Riley crossover can be designed. However, crossovers of order higher than 4 may have less usability due to their complexity and the increasing size of the peak in group delay around the crossover frequency.
