modulating signal applied to anode

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Amplitude modulation > by means of discharge device having at least three electrodes > carrier applied to control grid > modulating signal applied to anode

CPC:

Amplitude modulation (H03C5/00, H03C7/00 take precedence) > by means of discharge device having at least three electrodes (H03C1/28 - H03C1/34, H03C1/50, H03C1/52, H03C1/62 take precedence) > carrier applied to control grid > modulating signal applied to anode

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