AB  - It is known that the harmonic distortion of an active filter is greater than the distortion of the operational amplifier itself. Positive- and negative-feedback linear filters, namely, Butterworth, Chebyshev, Bessel, and band-pass filters, are analyzed. The distortion multiplication factor K(d) is defined and plotted versus frequency. The maximum values of K(d) found for several filter configurations by means of a computer program are given in a form useful for filter designers.
