Absorptive Bessel Lowpass Filters
RLC Electronics' 4th Order Absorptive Bessel Filters provide the excellent group delay response of Bessel filters while maintaining impedance matching far into the stop band. Lossy elements are designed into these filters, resulting in a response that closely mimics the classic Bessel in both amplitude and phase. Applications include designs of digital systems where truthful reproduction of waveforms is important. The filters also may be used to reduce the impact of high order distortion and noise lightwave receivers.
