I would like to fit a sine wave trendline to the chart, and also get the amplitude and the period from the formula of the sine wave. If you integrate a period of the sine wave vs time and divide by total time of that period, you get a mean average signal size. You know the period of the wave is 3 seconds, the sine wave will repeat every 3 seconds. k is a repeating integer value that ranges from 0 to p–1. If the sine wave being measured is symmetrical either side of zero volts (or zero amperes), meaning that the dc level or dc component of the wave is zero volts, then the peak value must be the same as the amplitude, that is half of the peak to peak value. The velocity of a wave is calculated as the multiplication of wavelength and frequency. The general sine and cosine graphs will be … It's not the ideal two sided sine wave. Log InorSign Up. This figure shows how to consider different points on the sine wave … Time period of one sine wave = 40 * 10^-6 * 50 = 2ms. Select the waveform. A sine wave of 1500 Hz. P1.
