Full Title

Full titles differ between systems:

IPC:

Generation of oscillations by combining unmodulated signals of different frequencies > by beating unmodulated signals of different frequencies > using several similar stages

CPC:

Generation of oscillations by combining unmodulated signals of different frequencies (H03B19/00 takes precedence; frequency changing circuits in general H03D) > by beating unmodulated signals of different frequencies > using several similar stages

No child classifications to compare. This is a leaf node in both IPC and CPC.
