I've made an effort to think of an illustration of a tool that might operate poorly because of that fuzz, but absolutely nothing relates to mind. Whenever you drive noise that significantly down, it gets to be inconsequential to most circuits, And that's why linear regulators are still used, despite their inefficiency.
Voltage that does not increase and reduce smoothly will trigger variations in speed. The measures to the output of the modified sine wave are from the many hundreds of Hz location, read here so a modified-sine UPS is probably going to induce a improve in just how the motor operates that you simply can actually listen to.
