DIFF Subgroup
G06G 7/40

of partial differential equations (analogue computers for specific processes, systems or devices, e.g. simulators, G06G7/48)

Introduced: September 1968

Title

Titles differ between systems:

IPC: of partial differential equations

CPC: of partial differential equations (analogue computers for specific processes, systems or devices, e.g. simulators, G06G7/48)

Full Title

Full titles differ between systems:

IPC:

Devices in which the computing operation is performed by varying electric or magnetic quantities > Arrangements for performing computing operations, e.g. amplifiers specially adapted therefor > for solving of equations > of differential or integral equations > of partial differential equations

CPC:

Devices in which the computing operation is performed by varying electric or magnetic quantities > Arrangements for performing computing operations, e.g. amplifiers specially adapted therefor > for solving of equations > of differential or integral equations > of partial differential equations (analogue computers for specific processes, systems or devices, e.g. simulators, G06G7/48)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
