Full Title
Amplitude modulation > by means of semiconductor device having at least three electrodes
Classification Context
- Section:
- ELECTRICITY
- Class:
- ELECTRONIC CIRCUITRY
- Subclass:
- MODULATION
Scope Notes
Limiting references: Amplitude modulation by means of light-sensitive element Amplitude modulation by converting angle modulation to amplitude modulation Amplitude modulators in which carrier or one side-band are wholly or partially suppressed Amplitude modulators in which amplitude of carrier component in output is dependent upon strength of modulating signal, e.g. no carrier output when no modulating signal is present
