An experiment for observing intensity correlations from pseudothermal light sources is described. Analog rather than digital electronics is used. Results are obtained that show clearly the relation between amplitude interference and intensity interference. Gaussian, two-slit, and uniform-brightness disk sources are used. The application of this experiment to the understanding of stellar-intensity interferometry is pointed out.
