Every great active filter has a carefully selected operational amplifier to create an optimum solution. Understanding the relationship between the filter’s quality factor (Q), circuit gain (G), and ...

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 ...
