Figure 19. Pulse Width Modulator

VCC = 5V

Top Trace: Modulation 1V/Div.

TIME = 0.2 ms/DIV.

Bottom Trace: Output Voltage 2V/Div.

RA = 9.1kΩ

C = 0.01

PULSE POSITION MODULATOR

This application uses the timer connected for astable operation, as in Figure 21, 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 22 shows the waveforms generated for a triangle wave

modulation signal.
