The Beard "I WAS bald!"), Elaine angrily throws his wig out the window, and the homeless guy picks it up. After the date, Elaine invites Robert to her apartment. Wig-less George tells Jerry he is again himself, and will continue seeing the bald woman; he then tells Jerry, who is going to take the lie detector test, that a lie is not a lie if he believes it. Later, Elaine triumphantly announces to Jerry that Robert has defected from his team and that the conversion went perfectly ("Sex and shopping"). Afterwards, Kramer is still doing police lineups. Jerry takes the lie detector
Product detector 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. Product detector A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a local oscillator, hence the name. A product detector is a frequency mixer. Product detectors can be designed to accept either
