The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Abstract: To solve the problem of inaccurate demodulation resulted from the system uncertain phase shift which exists in the demodulation process of the amplitude modulation (AM) for an inductance ...

Abstract: This paper presents a novel technique of amplitude modulation which is based on a second-order oscillator circuit. By using the multi-time technique to analyze a second-order system for time ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
