AC transmission circuit stability
To ensure stability of the feedback loop shown in
block diagram form in figure 13 two capacitors are
required. Figure 14 includes these capacitors Cc
and Ch.
AC - DC separation
The high pass filter capacitor C
AC
provides the
separation between DC circuits and AC circuits. A
CAC value of 100mF will position the low end fre-
quency response 3dB break point at 7Hz,
