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
Detector (radio) local oscillator, hence the name. By heterodyning, the received signal is mixed (in some type of nonlinear device) with a signal from the local oscillator, to give sum and difference frequencies to the signals being mixed, just as a "first mixer" stage in a superhet would produce an intermediate frequency; the beat frequency in this case, the low frequency modulating signal is recovered and the unwanted high frequencies filtered out from the output of the product detector. Product detector circuits are and so essentially ring modulators or synchronous detectors and closely related to some phase-sensitive detector circuits. They can be
