The figure shows the Schmidt shaping circuit that changes the sinusoidal voltage into the rectangular wave. The sinusoidal voltage which is reduced by the transformer adds to the base electrode of VT1 directly. In the positive half cycle of the alternating current, the diode VD conducts, the base electrode electric potential of VT1 is positive, so the VT1 cuts off, VT2 conducts. In the negative half cycle of the alternating current, the base electrode electric potential of VT1 is negative, VT1 conducts and the 5OHz rectangular wave is output by the collector electrode of VT2.
