DEFINITION

Classification: 329/333

Including plural detector diodes (e.g., ratio detector type):

(under subclass 332) Subject matter which additionally utilizes a plurality of diodes in demodulation.

(1) Note. An example of this structure is a ratio detector where the ratio of a pair of diode rectified currents is proportional to frequency variations of an input signal.
