H03D 3/24

Modifications of demodulators to reject or remove amplitude variations by means of locked-in oscillator circuits

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Demodulation of angle-modulated oscillations > by detecting phase difference between two signals obtained from input signal > Modifications of demodulators to reject or remove amplitude variations by means of locked-in oscillator circuits

CPC:

Demodulation of angle-, modulated oscillations (H03D5/00, H03D9/00, H03D11/00 take precedence) > by detecting phase difference between two signals obtained from input signal (H03D3/28 - H03D3/32 take precedence; ; limiting arrangements H03G11/00) > Modifications of demodulators to reject or remove amplitude variations by means of locked-in oscillator circuits

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
