of semiconductor devices

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Demodulation of amplitude-modulated oscillations > by means of non-linear elements having more than two poles > of semiconductor devices

CPC:

Demodulation of amplitude-modulated oscillations (H03D5/00, H03D9/00, H03D11/00 take precedence) > by means of non-linear elements having more than two poles (H03D1/22, H03D1/26, H03D1/28 take precedence) > of semiconductor devices

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