==Advantages and disadvantages== The product demodulator has some advantages over an envelope detector for AM signal reception. * The product demodulator can decode [[overmodulation|overmodulated]] AM and AM with suppressed carrier. * A signal demodulated with a product detector will have a higher [[signal-to-noise ratio]] than the same signal demodulated with an envelope detector. On the other hand, the envelope detector is a simple and relatively inexpensive circuit, and it can provide higher fidelity, since there is no possibility of mistuning the local oscillator. A product detector (or equivalent) is needed to demodulate SSB signals. {{DEFAULTSORT:Product Detector}} [[Category:Frequency mixers]] [[Category:Communication circuits]] [[Category:Demodulation]] [[de:Amplitudenmodulation#Koh.C3.A4rente_Demodulation]]
