DIFF Subgroup
H03K 5/08

by limiting; by thresholding; by slicing, i.e. combined limiting and thresholding (H03K5/07 takes precedence; comparing one pulse with another H03K5/22; providing a determined threshold for switching H03K17/30)

Introduced: September 1968

Title

Titles differ between systems:

IPC: by limiting, by thresholding, by slicing, i.e. combined limiting and thresholding

CPC: by limiting; by thresholding; by slicing, i.e. combined limiting and thresholding (H03K5/07 takes precedence; comparing one pulse with another H03K5/22; providing a determined threshold for switching H03K17/30)

Full Title

Full titles differ between systems:

IPC:

Manipulation of pulses not covered by one of the other main groups of this subclass > Shaping pulses > by limiting, by thresholding, by slicing, i.e. combined limiting and thresholding

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) > Shaping pulses (discrimination against noise or interference H03K5/125) > by limiting; by thresholding; by slicing, i.e. combined limiting and thresholding (H03K5/07 takes precedence; comparing one pulse with another H03K5/22; providing a determined threshold for switching H03K17/30)

Of 1 combined children, 0 exist in both systems.
