IPC: with intermediate conversion to time interval

CPC: with intermediate conversion to time interval (H03M1/64 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Analogue/digital conversion; Digital/analogue conversion > Analogue/digital converters > with intermediate conversion to time interval

CPC:

Analogue/digital conversion; Digital/analogue conversion (conversion of analogue values to or from differential modulation H03M3/00) > Analogue/digital converters ( H03M1/10 take precedence) > with intermediate conversion to time interval (H03M1/64 takes precedence)

Of 6 combined children, 4 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1985.
