The Jeremy Kyle Show test Jeremy Kyle performed a live on stage test with the question "are you, or have you ever been a llama?" which he replied yes, which was identified as a lie. Research indicates that results are little better than chance. A critic in "The Guardian" comments that "Kyle regularly claims the lie detector is 96 per cent accurate, whereas a 1997 survey of 421 psychologists estimated it to be 61 per cent. Or not much better than chance." An on-screen disclaimer is now shown before lie detector results are read out on the programme, stating, "The lie detector is designed
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
