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 shows a triangular-wave modulation signal for such a circuit; however, any wave shape can be used.
