Abstract
An amplitude and phase demodulator circuit for signals with very low modulation index, including: amplifier circuitry adapted to amplify a modulated signal coming from a transmitter, the modulated signal being composed by a carrier and by a modulating component, circuitry adapted to cancel said carrier from said modulated signal; the circuitry adapted to cancel the carrier receiving in input the output signal of the amplifier circuitry and a sync signal coming from the transmitter, the output signal of the amplifier circuitry being delivered to receiver circuitry.
