New VLBI systems are under development in many countries in preparation for large dedicated arrays, including orbiting radio telescopes to be launched in the 1990s. In particular, several new recording systems and correlators are being constructed: t

Digital correlators have been analyzed in considerable detail for cases in which the components behave ideally. Here we consider the effects of the major deviations from ideal behavior which are encountered in practice. Attention is restricted to thr

The frequency responses of the receiving channels of a radio astronomy synthesis array and, in particular, the variations between them for different antennas are factors that limit the accuracy and sensitivity of the instrument. A response that appro

CYGNUS X-3 was observed at 2.8 cm (10,690 MHz) on each of four days during its early September 1972 outburst using the new five-element minimum redundancy array at Stanford University1. The instrument employs equatorially-mounted 18.3 m diameter para
