A Single Detector for CW Modulated Signals
P Hari Krishna Prasad · IETE Journal of Education · 2005
This paper presents a single detector circuit for recovering the modulating signal from the amplitude modulated (AM) carrier and frequency modulated (FM) carrier. The circuit works on the principle of converting the modulated carrier in to a pulse modulated signal and then passing the signal through a low pass Filter to extract the original modulating signal. The mathematical details of the suggested scheme and its comparison with the conventional methods of detection are also presented.
