H03D3/08 - CPC Classification

Classification description:

Demodulation of angle-, frequency- or phase- modulated oscillations by detecting phase difference between two signals obtained from input signal by combining signals additively or in product demodulators by means of diodes, e.g. Foster-Seeley discriminator

Sub-classes:

H03D3/10 » in which the diodes are simultaneously conducting during the same half period of the signal, e.g. radio detector 0
