FI (Note)/(Index) list

Descriptions for H03D and notes/indexes are displayed on this screen.

H03D DEMODULATION OR TRANSFERENCE OF MODULATION FROM ONE CARRIER TO ANOTHER (masers, lasers H01S; circuits capable of acting both as modulator and demodulator H03C, e g  balanced modulators H03C 1/54; details applicable to both modulators and frequency-changers H03C; demodulating pulses which have been modulated with a continuously-variable signal H03K 9/00; transforming types of pulse modulation H03K 11/00; relay systems, e g  repeater stations H04B 7/14; demodulators adapted for digitally modulated-carrier systems H04L 27/00; synchronous demodulators adapted for colour television H04N 9/66)

Note(s)
This subclass covers only:
    demodulation or transference of signals modulated on a sinusoidal carrier or on electromagnetic waves;comparing phase or frequency of two mutually-independent oscillations.
