particular, the input capacitance 3 C and the feedback resistance
Rn give a transfer function with a zero in the origin and a highfrequency
pole (at f = 1/3RnC) realizing the behavior of a real
differentiator. Finally, the variable resistance gives an additional
gain corresponding to the Gs parameter indicated in Table IV.
The chosen power amplifier and core magnetic material allow a
very compact filter layout.
The used circuit parameters are reported in Table V.
Table IV gives, for each filter section, the expression of the
corresponding parameters
