Abstract
1,258,310. Transistor demodulator circuits. TELEFONAKTIEBOLAGET L.M. ERICSSON. 27 March, 1969 [28 March, 1968], No. 16237/69. Heading H3T. A demodulator for amplitude modulated signals comprises two transistors connected in a long tail pair configuration with a capacitor C connected across the common emitter resistor R 3 to decouple the carrier. Rectification is effected by the base-emitter diodes the modulated signal being fed to one input I a , and a reference direct potential being applied to the other input R a .
