Then divided one by the other to get the crest factor. That is displayed in row 3. I added a sine wave to make sure the figures were working out as I expected. (Sine waves have crest factors of 1.414 i.e. SQRT(2).)

WebMar 23, 2006 · For this I need to find the peak values of the wave. Starting with the maximum value (x1) the wave will decrease to a trough and increase to a 2nd peak (x2) followed by (x3).... (xn). I would like to know if a formula can be written to determine the peak values of x1-xn. I can supply a sample wave form with the correct values of the peaks.

WebMay 30, 2014 · After all I am entering a positive number for the phase shift, represented by theta in the equation below. The equation for a sine wave is: y (t) = A *sin (ωt+θ) I have a file uploaded. If it helps, in cells C29 and D29, I have checkboxes so that you can show or hide the sine wave that is being graphed in column C or D. WebJan 6, 2012 · After the FFT you need to calculate the magnitude of the first N/2 complex output bins ( sqrt (real*real+imag*imag )). If the fundamental peak is at bin N, then the second and third harmonics will be at bins 2*N and 3*N. That is done through =IMABS (D1). WebThe second term is the only sine term in the series. The third term (cosine terms) has only even harmonics. We used Excel to calculate the the frequency coefficients to n=10, the tenth harmonic, then summed up the … g7j2a2b-b
