Abstract: An improved synchronous demodulation method based on d-axis response high-frequency (HF) voltage is proposed for sensorless starting control of three-stage synchronous machine (TSSM) in the ...

Abstract: Synchronous demodulation (SD) is the signal recovery method of choice when the input envelope signal is modulated by either a pure sine wave or a square wave. SD is less efficient for pulsed ...

The theoretical and practical requirements for introducing synchronous demodulation into domestic receivers for MF/LF broadcasting are discussed. The difficulties encountered in the construction and ...

Implement an amplitude modulator in MATLAB without using inbuilt functions. Plot both time and frequency domain plots of the amplitude modulated output for various modulation indices. Implement a ...
