Figure 9 gives an easy selection for RA, RB and
C
Similar to the PWM circuit of Figure 5 the astable
circuit can be configured with modulation of the
control input as shown in Figure 10. The result is a
pulse position modulated, PPM, circuit where the
pulse position is altered by the control input voltage.
