#125800 - Hi All, Responding to: ???'s previous message |
When I went to Uni, we had to prove that result in the first week.
For any periodic signal, its the square root of the average value of the square over 1 period of the signal. Its 'A' level calculus. Steve If you perhaps look at my thread that you closed down, I tried repeatedly to show the same equation and hence,: http://en.wikipedia.org/wiki/Root_mean_square Please check it out, It happens to be the same equation that Steve is proposing, Am I wrong so far or am I right?? Furthermore, 1/root2 is a constant, what do we do when our wave changes from pure sinewave to squarewave, can this equation handle squarewaves as well as sines??? Clearly, 1/root2 does not work anymore does it??, for the squarewave.We have to integrate over the waves period to obtain another constant which will satisfy r.m.s. value for the square wave, correct?? Over to you Steve |
