WebMay 28, 2024 · FvM said: -3 dB (half power) cutoff frequency criterion is used for filters with non-ripple passband. For equi-ripple Chebyshev and elliptical (Cauer) filters, the ripple related criterion described by LvW is used by most authors, see graph below. Some books are however calculating a -3 dB cutoff frequency for these filters. WebThis paper introduces two new high-input impedance electronically tunable voltage-mode (VM) multifunction second-order architectures with band-pass (BP), low-pass (LP), and high-pass (HP) filters. Both proposed architectures have one input and five outputs, implemented employing three commercial LT1228 integrated circuits (ICs), two grounded capacitors, …

WebSep 5, 2024 · At a single frequency, this circuit can be transformed. However, as a filter, i.e. a circuit that reacts differently to different frequencies, it is not equivalent to a 2nd order RLC filter. A 2nd order filter has an asymptotic roll-off of -40 dB / decade. A 3rd order filter, such as this, has an asymptotic roll-off of -60 dB / decade.
