This circuit is a two-pole, active lowpass filter. The DC path from input E1 to output Eo is via R1 alone and does not involve the op amp. Because C1 and C2 are DC blocks from the op amp to the signal ...
The circuit in Figure 1 was given to me some while ago as a three-pole, active 1 dB Chebyshev lowpass filter. I never confirmed that its transfer function complied with the Chebyshev polynomial, but ...
