EE Help

I have to do this prelab but I havent learned it in my lecture yet. Could someone please try and tell me how to do this problem? Thanks

whats the rms voltage of the following waveforum: 6 Vpp square with no DC value at 2k Hz.

You need to multiply the peak-to-peak voltage by a factor to get the rms voltage. I can't remember what it is for a square wave. For sine waves, it's sqrt(2)/2. You should be able to find it pretty easily. Or just derive it.

Edit: I'm an idiot. For a square wave, the peak-to-peak and rms voltages are the same. I.E. the conversion factor is 1.

A square wave's average value is the same at its peak value (or for that matter its RMS value)
