In any receiver a key element is the detector. Its purpose is to remove the modulation from the carrier to give the audio frequency representation of the signal. Synchronous detection is used for the detection or demodulation of Amplitude Modulation (AM). This form of modulation is still widely used for broadcasting on the long, medium and short wave bands despite the fact that there are more efficient forms of modulation that can be used today. Synchronous detectors are considerably more complex than simple envelope detectors. 40525 Synchronous AM Detector is a experiment platform with both modulator and synchronous detector for demodulation. This provide Students the basic knowledge of how a synchronous detector works, and students can also measure the modulation index and observe thedifferent waveform for Amplitude Modulation. 40525 comes with inbuilt Power Supply.
