GB5271.19-86
This vocabulary consists of about twenty parts. This part describes the common concepts and definitions of data processing related to analog and mixed operations. These definitions describe the concepts of analog and mixed operators, function generators, converters and the working methods of the above components. This part uses the term "functional component" to describe the function performed by a certain mechanism. If the above function can be performed by a device in any special case, the term "equipment" is considered to be the same as the term functional component. This part of this vocabulary is equivalent to the international standard ISO2382/19-1980 "Data processing vocabulary--Part 19: Analog computing".
1.2 Scope
This vocabulary selects terms and concise definitions of some concepts in the field of data processing, and clarifies the relationship between different concepts to facilitate domestic and international exchanges.
The vocabulary covers all major aspects of data processing, including the main processing processes and types of equipment used, data representation, data organization, data description, computer programming and operation, external devices, data communication and other special applications. 1.3 Applicable scope
This standard applies to the design, production, use, maintenance, management, scientific research, teaching and publishing of various fields related to electronic computers and information processing.

analog adder
A functional unit whose output analog variable is equal to the sum or weighted sum of two or more input analog variables. 19.01.04
inverter
inverter
A functional unit whose output analog variable is equal to the input analog variable in absolute value but opposite in sign. coefficient unit
coefficient unit
A functional unit whose output analog variable is equal to the input analog variable multiplied by a constant. analog multiplier
anolog multiplier
A functional unit whose output analog variable is proportional to the product of two input analog variables. NOTE: This term may also be applied to a unit that is capable of performing multiple multiplications, such as a multiplier. Quarter-squares multiplier

A functional unit whose output analog variable is equal to the integral of the weighted sum of the input analog variables over time, or the integral of another input analog variable. Function generator
function generator
GB 5271.19--86
A functional unit whose output analog variable is equal to a function of the input analog variables. 19.01.12
Fixed function generator
fixed function generator
A function generator whose function cannot be changed arbitrarily by the user. Variable function generator
variable function generator
A function generator whose function can be set by the user before operation or during operation. 19.01.14 comparator (in analog computing) A functional unit that compares two analog variables and displays the result of the comparison. 19.01.15 limiter A functional unit that prevents an analog variable from exceeding a certain limit. 19.01.16 dead-zone unit A functional unit whose output analog variable remains constant within a specified range of the input* analog variable. resolver A functional unit whose input* analog variable is the polar coordinates of a point and whose output analog variable is the rectangular coordinates of that point, or vice versa. analog-to-digital converter ADC (abbreviation) A functional unit that converts data from analog representation to digital representation. Digital-to-analog converter DAC (abbreviation) A functional unit that converts data from digital representation to analog representation. 19.01.20 Track and hold unit Track and store unit Track and store unit A functional unit whose output analog variable is either equal to the input analog variable or to the sampled value of this variable selected by an external Boolean signal. Note: When tracking, the unit tracks the input analog variable. When holding, it holds the value of the input analog variable at the moment of switching. 19.02 Potentiometer set mode Potentiometer set mode A preparatory state of an analog computer, in which the coefficients of the question are set. 19.02.02
Static test mode
static test modeWww.bzxZ.net

Initial condition mode
initial condition mode
Reset mode
reset imode
GB5271.19-86
A state of operation of a simulated computer in which initial conditions are set but the integrator is not yet operational. compute mode
compute mode
operate mode
A state of operation of a simulated computer in the process of solving a problem. 19.02.05 hold mode

repetitive operation
Automatically repeating an operation to find a solution to a system of equations with a fixed combination of initial conditions and other parameters.

Iterative operation
Automatic sequential operation
automatic sequential operation Repeat the same algorithm to find the solution of a system of equations with a series of successive initial conditions or other parameter combinations. And auxiliary calculations based on a predetermined set of iterative rules are used to select each successive combination.
