This application uses the timer connected for astable operation, as in Figure 1, with a modulating signal again applied to the control voltage terminal. The pulse position varies with the modulating signal, since the threshold voltage and hence the time delay is varied. Figure 2 shows the waveforms generated for a triangle wave modulation signal.
VCC = 5V
TIME = 0.1 ms/DIV.
RA = 3.9kΩ
RB = 3kΩ
C = 0.01µF
