DIFF Subgroup
H03K 5/13

Arrangements having a single output and transforming input signals into pulses delivered at desired time intervals

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Manipulation of pulses not covered by one of the other main groups of this subclass > Arrangements having a single output and transforming input signals into pulses delivered at desired time intervals

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 having a single output and transforming input signals into pulses delivered at desired time intervals

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
