Combining two PWM signals together

Other Hardware General Electronics

Hi all,

I have two independant PWM signals that I would like to combine to get a an output as illustrated below:

PWMs combined
PWMs combined1227×637 39.8 KB

I have generated both the PWM signals successfully, just need some guidance on the circuit required to combine them?

Thanks in advance :slight_smile:

Google "resistor adder".
If you use a 10k lin pot, then you can vary the mixing ratio.
Outside pins of the pot to the two PWM outputs, wiper is output.
