by means of synchronous gating arrangements

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 > by means of synchronous gating arrangements

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) > by means of synchronous gating arrangements

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
