5, with a good wide frequency response characteristics. Parameters determined: Rz R3, CL C2, R Rz/2, c; ZCL,! ,. 1/2Tr Rz. Ci, the attenuation pole at the resonance. If you deviate from the above conditions, the error should be noted that the various components can not be obtained when the maximum attenuation fan, lr-iJ.
