Pulse Width Modulation and Demodulation

[Justin_P]

Overview: This vi converts a sine wave into a PWM signal and then demodulates that signal back into a sign wave.

---

Description:  First a Simulate Signal Express VI is used to create a sine wave signal. That siganl is then fed into the Square Wave VI. The signal leaving the Square Wave VI is sent to a waveform graph that shows the PWM signal. The same signal out of the Square Wave VI is also sent to a Timing and Transitions Measurements Express VI, that demodulates the PWM signal back into the sine wave signal.

Requirements: LabVIEW 2012 (or compatible). Hardware: none. 

---

Steps to Implement or Execute Code:

1. Run the VI.
2. Look on the graphs.
