Abstract : A semi-automatic correlator that uses a matrix network for the multiplication operation is described. The source data in the form of a numerical table is inserted into the correlator by a keyboard device. The correlator includes a multiplication matrix designed with square-loop ferrites, transistorized block generators and amplifiers, and also ferrite-diode registers with a compensating core in each cell. A block diagram and a principal circuit of the correlator are presented, and its operation is described. The maximum relative error depends on the number of discrete levels in the multiplication matrix. The correlator speed of operation is determined by the product read time; average time of one reading is 0.1--0.15 sec.
