DIFF Subgroup
H03B 11/02 excited by spark (spark gaps therefor H01T9/00)
Introduced: September 1968
Title
Titles differ between systems:
IPC: excited by spark
CPC: excited by spark (spark gaps therefor H01T9/00)
Full Title
Full titles differ between systems:
IPC:
Generation of oscillations using a shock-excited tuned circuit > excited by spark
CPC:
Generation of oscillations using a shock-excited tuned circuit (with feedback H03B5/00) > excited by spark (spark gaps therefor H01T9/00)
No child classifications to compare. This is a leaf node in both IPC and CPC.
