Abstract

PURPOSE:To obtain the timing playback waves having different phase difference, by converting the timing component of input data picked up into a sinusoidal wave and by using this sinusoidal wave and threshold voltage. CONSTITUTION:The input data are input to a bandpass filter 2 where the timing signal frequency components are picked up. After this is converted into a rectangular wave (a) at a playback amplifier 3, it is made to a sinusoidal wave (b) at a resonance circuit 4 and input to a playback amplifier 5. A threshold value Vth is given as another input of the playback amplifier 5, and when the threshold value is Vth 1, the timing playback wave of phase difference tau1 is obtained, and when the threshold value is Vth 2, the timing playback wave of phase difference tau2 is obtained.
