FIGURE 3-11. GRAPHS OF POSSIBLE BOP INPUT/OUTPUT WAVESHAPES
NOTE: The phase shift between the input and output signals of the BOP unit working as an
amplifier is 0° in the non-inverting configuration (inherent) or 180° in the inverting con-
figuration. This is only for input signal frequencies smaller than 1/10 of the 3dB band-
width frequency listed in Section 1, Table 1-3.
The basic programming circuit with which all the waveforms shown in FIG. 3-11 can be pro-
duced is shown in FIG. 3-12. Since all input signals in FIG. 3-11 are shown with a ±10 volt ampli-
