Full Title
Full titles differ between systems:
IPC:
Electric signal transmission systems > in which transmission is by pulses > using a variable number of pulses in a train > operating on dynamo-electric devices, e.g. step motor
CPC:
Electric signal transmission systems (G08C17/00 takes precedence) > in which transmission is by pulses > using a variable number of pulses in a train > operating on dynamo-electric devices, e.g. step motor
No child classifications to compare. This is a leaf node in both IPC and CPC.
