Observations of 46 suspected spectroscopic or visual binary stars obtained using a television speckle interferometer with digital data accumulation on the 6-m telescope of the Special Astrophysical Observatory at Nizhni Arkhyz during April and June, 1983, are reported. The television system employs a 256 x 256 raster and 50-Hz frame rate and the two-dimensional autocorrelation-function (ACF) algorithm of Blazit et al. (1975); filters used have central wavelengths and bandwidths 600 and 16 nm (orange), 656 and 12 nm (red), 525 and 10 nm (green), and 435 and 12 nm (blue). A typical three-dimensional ACF map of binaries are given in a table; and the 21 unresolved objects are listed separately. The separations of the resolved pairs range from 29 to 270 marcsecs.
