using an operational amplifier comprising a capacitor or a resistor in the feedback loop

Introduced: January 1980

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 integration or differentiation > using capacitive elements > using an operational amplifier comprising a capacitor or a resistor in the feedback loop

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 integration or differentiation; for forming integrals (G06G7/19 takes precedence) > using capacitive elements > using an operational amplifier comprising a capacitor or a resistor in the feedback loop

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
