7.2.3 Pulse-Position Modulation
As shown in Figure 7-5, any of these timers can be used as a pulse-position modulator. This application modulates the threshold voltage and thereby the time delay of a free-running oscillator. Figure 7-6 and Figure 7-7 shows the output frequency and duty cycle versus control voltage.
A. The modulating signal can be
direct or capacitively coupled to CONT. For direct coupling, consider the
effects of modulation source voltage and impedance on the bias of the
timer.
