I've decided to run my computer system off a pure sinewave inverter acting as a double conversion UPS as my AC line voltage fluctuates a lot and I don't want to cause damage to my expensive equipment.
Now the AC waveform is a very clean sinewave as can be seen on my oscilloscope, however the inverter makes an audible high pitched buzzing sound and I'm hearing that exact same sound coming through my studio monitors.
My question is, how do I determine the frequency of this noise and how do I filter it?
