Introduced: January 1980
Title
Titles differ between systems:
IPC: by means of electromechanical devices
CPC: by means of electromechanical devices (H03D3/16 takes precedence)
Full Title
Full titles differ between systems:
IPC:
Demodulation of angle-modulated oscillations > by means of electromechanical devices
CPC:
Demodulation of angle-, modulated oscillations (H03D5/00, H03D9/00, H03D11/00 take precedence) > by means of electromechanical devices (H03D3/16 takes precedence)
No child classifications to compare. This is a leaf node in both IPC and CPC.
