The effect of bandpass limiting on noise with a Gaussian spectrum

The effect of limiting on the spectrum of Gaussian noise is computed where the noise has a Gaussian spectrum before limiting, and the output spectral density is plotted for various noise-to-limit level ratios. A decibel scale displays the spectral spreading due to limiting with an accuracy not available in previously published data. The results have application to radar and sonar signal processors which attempt to detect targets in clutter.
