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:
Demodulation of angle-modulated oscillations > by means of electromechanical devices
Demodulation of angle-, modulated oscillations (H03D5/00, H03D9/00, H03D11/00 take precedence) > by means of electromechanical devices (H03D3/16 takes precedence)
Additional Content IPC
Demodulation of angle-modulated oscillations by detecting phase difference between two signals obtained from input signal by combining signals additively or in product demodulators by means of electromechanical resonators
No child classifications to compare. This is a leaf node in both IPC and CPC.
