Abstract :
The closed-form design formulas for some lower-order elliptic approximation functions are derived in terms of desired cutoff frequency and ripple factor. Transfer function poles and zeros are obtained by means of simple formulas, thus freeing the designer from a reliance on extensive tables or complex computer programs.
