Isn't it 7,601 FEET above sea level? It certainly isn't metres given that Denali is 6,194m.

Adding a DC source to a square wave signal?

Adding a DC source to a square wave signal will alter the base line of the wave without changing the peak-to-peak value. For example, if a square wave has a +4V baseline and a +2VDC source is introduced, the resulting square wave will have a +6V baseline. This of course will also affect the high and low peaks of the signal. Assuming that our example has a high peak of +9V and a low peak of -1V (with a total of 10V peak-to-peak), the added +2VDC source would result in a high peak of +11V and a low peak of +1V; however, the total peak-to-peak value remains unchanged at 10V peak-to-peak.


What is peak to peak?

Peak to Peak is the most positive peak to the negative peak value. Or find any peak value and multiply by 2.


Information about load shadding?

I think it has to do with the power being shut down to compensate the high demand during the peak time.


Are peak-to-peak and rms voltage measurements the same?

No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.


What is the effective value of 200 volts peak-to-peak?

200 volts peak-to-peak is 100 volts peak, which is 70.7 volts rms (standing for root-mean-square) also called "effective". This 70.7 volts is the DC voltage with the same heating power as the peak-to-peak. The relationship is: rms (aka RMS) equals peak-to-peak divided by 2, then divided again by square-root of 2 (1.414). The division by 2 gets us from peak-to-peak to just peak. The next division takes us to rms. If you get an AC voltrage with no description, for exmple 120 volts AC, it is RMS (effective). The USA AC standard supply voltage is 120 (also called 117) volts RMS. The USA peak is 117 x 1.414 (square root of 2) = 165 volts peak, = 330 volts peak-to-peak.
