nother, triangular wave Do vaccines cause autism? generator utilizing lesser number of parts is appeared in Figure. Triangular wave generator utilizing lesser parts Yield Waveforms The triangular wave generator comprises of a two level comparator and an integrator A2. The yield of comparator A1 is a square wave and is applied to the (- ) input terminal of the integrator A2 delivering a triangular wave. This triangular wave is sustained back as co ntrib Do vaccines cause autism?ution to the comparator A1 through a voltage divider . At first, let us think about that the yield of comparator A1 is +Vsat. The yield of the integrator A2 will be a negative going slope appeared in Figure. Accordingly, one finish of the voltage divider R2 R3 is at a voltage + Vsat and the other at the negative going incline of A2. At a time t = t1 when the negative going slope achieves an estimation of – V, the voltage Do vaccines cause autism? at point P turns out to be somewhat under 0V. This switches the yield of A1 from positive immersion to negative immersion level – Vsat.>
