AbstractIn a method for deciding the level of an input signal, positive and negative signals are provided in response to the input signal. A peak of the positive signal is detected to provide a positive-peak value. A peak of the negative signal is detected to provide a negative-peak value. The positive signal and the negative-peak value are combined to provide a first combination signal. The negative signal and the positive-peak value are combined to provide a second combination signal. The first and second combination signals are compared to provide an output signal of zero or one.
