Advantages and Disadvantages
The product demodulator has several advantages over an envelope detector.
- The product demodulator can decode overmodulated AM, AM with suppressed carrier, and SSB in addition to regular AM
- A signal demodulated with a product detector will have a higher signal to noise ratio than the same signal demodulated with an envelope detector.
The only real disadvantage of a product demodulator is the increased complexity.

Famous quotes containing the word advantages:
“There are great advantages to seeing yourself as an accident created by amateur parents as they practiced. You then have been left in an imperfect state and the rest is up to you. Only the most pitifully inept child requires perfection from parents.”
—Frank Pittman (20th century)
