Abstract :
The noise bandwidth BNof Butterworth, Bessel, and Chebyshev filters is tabulated. The Butterworth filter is shown to have the minimum BNto 3-dB bandwidth ratio for any secondorder filter. It is proven that BNis invariant when a low-pass to bandpass transformation is made. An error is corrected in recent tables of Chebyshev filters.
