The correlation of the microstructure of PSR 0809 + 74, 0950 + 08, and 1133 + 16 is studied on the basis of three-frequency simultaneous observations with a time resolution of 10 microsec. Two types of microstructures are shown to exist: a small-scale one which does not correlate with a 20 MHz frequency difference, and a large-scale one which has a high correlation at different frequencies and a time delay which strictly adheres to the cold plasma dispersion law. Highly accurate dispersion measures are obtained from the correlated microstructure of these pulsars. The results are interpreted within the framework of the hollow-cone model.
