Hi guys
I'm trying to work out average and rms values of two different waveforms.
One is a sinusoidal wave, the other a ramped trapezoid (I think that's right).
The sinusoidal wave has a peak to peak voltage of 11v and the offset is alleged to be
9-15 = -6v. This is something I've been told to calculate in this way.
So what I have is a sine wave, starting at -6v, reaching a peak at -0.5v and a minimum of -11.5v? Average voltage = -6v? Rms = -0.5/sqrt(2) = -0.35v?? That isn't right, I know. Any help?
Now, the trapezoid...
Von = 11v, Voff = 45v, Ton = 0.022s.
Am I right in thinking...
For the triangular part (splitting the wave into a square and a triangle), I have Vave = 11+((45-11)/2) = 28v?? Vrms = 44/sqrt(3)?
For the square part...Vrms and Vave both = 11v?!
So how do I get a final result?
Any help would be appreciated.
