FIGURE 3-10. GRAPHS OF POSSIBLE INPUT/OUTPUT WAVESHAPES
The basic programming circuit used to produce the waveforms shown in Figure 3-10 is shown in
Figure 3-11. Since all input signals of Figure 3-10 are shown with a ±10 volts amplitude, the
basic programming circuit in Figure 3-11 must be modified if the external signal source cannot
produce 10 volts and if the full BOP output voltage swing is required.
