DIFF Subgroup
H03K 5/153

Arrangements in which a pulse is delivered at the instant when a predetermined characteristic of an input signal is present or at a fixed time interval after this instant (switching at zero crossing H03K17/13)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Arrangements in which a pulse is delivered at the instant when a predetermined characteristic of an input signal is present or at a fixed time interval after this instant

CPC: Arrangements in which a pulse is delivered at the instant when a predetermined characteristic of an input signal is present or at a fixed time interval after this instant (switching at zero crossing H03K17/13)

Full Title

Full titles differ between systems:

IPC:

Manipulation of pulses not covered by one of the other main groups of this subclass > Arrangements in which a pulse is delivered at the instant when a predetermined characteristic of an input signal is present or at a fixed time interval after this instant

CPC:

Manipulating of pulses not covered by one of the other main groups of this subclass (circuits with regenerative action H03K3/00, H03K4/00; by the use of non-linear magnetic or dielectric devices H03K3/45) > Arrangements in which a pulse is delivered at the instant when a predetermined characteristic of an input signal is present or at a fixed time interval after this instant (switching at zero crossing H03K17/13)

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

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1995.
