How to generate sine wave from PWM using Arduino/Simulink and RC low pass filter?
This video demonstrates how one can generate sine wave from PWM using Arduino/Simulink and RC low pass filter. For details see:https://ee-diary.blogspot.com/2020/10... sine signal generated by simulink is 400Hz sampled @10,000 samples/sec. It is low pass filtered using 3rd order RC filter. For comparison, we also show filtered and acquired sine signal through 1st and 2nd order RC filter.
