Circuitry for controlling amplitude response

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Details of television systems > Picture signal circuitry for video frequency region > Circuitry for controlling amplitude response

CPC:

Details of television systems (scanning details or combination thereof with generation of supply voltages H04N3/00) > Picture signal circuitry for video frequency region (cameras or camera modules comprising electronic image sensors, or control thereof H04N23/00) > Circuitry for controlling amplitude response

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
