    I am working on controlling proportional valves for cranes and I want to dithering pwm signals. I've been researching for a while and I think dither frequency must be around %10 of main pwm signals amplitude and more than main pwm's frequency. At the end these two signals will be collected and go to the valve. Is it wrong? Or is your method more efficient?

    I created a new thread for this topic from the replies to a 2 years old thread.
    Post #3 in this thread on another forum contains some valuable information.
