Abstract
Abstract A device for performing one of integrating and differentiating discrete functions, arranged on the basis of reversible adders a number of which is equal to a number of points defining the discrete function, each of the reversible adders comprises at least four reactance components having a common connection point whose self admittance is zero, while each two reactance components of all said reversible adders are combined in a rectangular matrix, each third reactance component of all adders being connected to one of the rows or horizontal buses of said rectangular matrix, each fourth reactance components being connected between one of the horizontal buses of the matrix and the ground.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
269 words
A device for performing one of integrating and differentiating a discrete function by numerical integration and differentiation, comprising: a plurality of reversible adders the number of which corresponds to a number of points of the determination interval defining the discrete function, each of said reversible adders including at least four reactance components having a common connection point whose self admittance is zero, two of said four reactance components of each said reversible adders being connected into a rectangular matrix including rows in the form of horizontal buses and columns in the form of vertical buses, the third of said four reactance components of each said reversible adder being connected to one of the horizontal buses of each said rectangular matrix, the fourth of said four reactance components of each said reversible adder being connected between one of the horizontal buses of said rectangular matrix and the ground, the device including a first set of terminal points connected to said horizontal buses and a second set of terminals connected said columns of the rectangular matrix whereby said first set and at least one of said second set of terminals corresponding to the integrating boundary conditions, is used as an input for performing integration of said discrete function, so that when a voltage representing said discrete function to be integrated is applied thereto, the integral of said function is provided at said second set of terminals, and whereby said second set is used as an input for performing differentation so that when said representing Voltage is applied thereto the differential of said function is provided at said first set of terminals.

Claim 3
Dependent Claim
68 words
A device for performing one of integrating and differentiating a discrete function as claimed in claim 1, in which additional reactance elements having free leads are connected to each horizontal bus and to each vertical bus of said rectangular matrix, the free leads of said elements being grounded, the ratings of said elements being so selected as to ensure zero self admittance at the points of their connection.
