Equivalent Statistical Bandwidths of Conventional Low-Pass Filters

The equivalent statistical bandwidths of low-pass Butterworth filters up to ten poles and Chebyshev filters up to eight poles for six different passband ripple levels have been computed and are tabulated along with the corresponding noise bandwidths. The results should be useful for evaluating the statistical error arising from power spectrum measurements such as encountered in the sensitivity analysis of microwave radiometer systems.
