Issue Details

I have the frequency and duty cycle of a signal. I would like to build a PWM signal using these values so that I can display it on a graph. How can I do this?

Solution

You can use the Simulate Signal Express VI, which is part of the Waveform Generation Sub-Palette. The signal Type should be Square.
