ArticIe gives design equations from which values of components were obtained. Critical damping (Q=0.71) is provided, Frequency can be tuned over range of two decades by changing resistor values simultaneously. Opamp can be one section of OP-11FY. For equivalent high-pass filter, transpose positions of resistors and capacitors.Gain is unity.-D. Van Dalsen, Need an Active Filter? Try These Design Aids, EDN Magazine, Nov. 5, 1978, p 105-110.
