COMPUTATIONAL CIRCUIT FOR MATHEMATICAL OR PHYSICAL VALUES IN ELECTRICAL FORM

摘要

Circuit arrangements for carrying out mathematical operations upon electrical signals by means of pulse sequences, the frequencies of which are proportional to desired computational results. Threshold-controlled comparison and decision units are provided for comparing the physical or electrical magitudes with output signals generated by associated threshold signal generators. The threshold-controlled comparison and decision units produce at their outputs logic 0 or 1 decisions. The threshold signal generators have output signals of predetermined relative amplitude frequencies. The outputs of the comparison and decision units are coupled to the inputs of a computationally adaptive configuration network, which includes a storage capability. The computationally adaptive configuration network transforms or configures the logic 0 or 1 sequences of the comparison and decision units to a resulting 0 or 1 sequence forming the output of the configuration network, and the relative pulse or pulse duration frequency of which is proportional to the computational result. The computational result output of the computationally adaptive configuration network can be connected to an output unit for displaying the computational results in analogue or digital form. In various embodiments of the invention computationally adaptive configuration networks are disclosed for performing multiplications, divisions, taking of roots and placing exponentaials, performing mathematical transforms on signals, and performing addition and subtraction.
