Typical Applications Characteristics (cont.)
Pulse Width Modulation
The operation of the timer can be modified by modulating the internal threshold and trigger voltages, which is accomplished
by applying an external voltage (or current) to CONT. Figure 10 shows a circuit for pulse-width modulation. A continuous
input pulse train triggers the monostable circuit, and a control signal modulates the threshold voltage. Figure 11 shows the
resulting output pulse-width modulation. While a sine-wave modulation signal is shown, any wave shape could be used.

Pulse Position Modulation
As shown in Figure 12, 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 13 shows a triangular-wave modulation
signal for such a circuit; however, any wave shape could be used.
