I want to desing a pwm class d PA, i think the open loop is no good, so i want to design a close loop class d.
the problem is: I want to know how the hormonic distortion comes up(I guess it caused by alias), and how the loop suppresses this distortion?
Any one know this ? or any book mentions this?
