This example shows how to find the root mean square (RMS) value of a sine wave, a square wave, and a rectangular pulse train usingrms. The waveforms in this example are discrete-time versions of their continuous-time counterparts. Create a sine wave with a frequency ofπ/4 rad/sample. ...
The RMS value is equal to 1/√2, as expected. Create a periodic square wave with a period of 0.1 seconds. The square wave values oscillate between −2 and 2. Get t = 0:0.01:1; x = 2*square(2*pi*10*t); stem(t,x,'filled') axis([0 1 -2.5 2.5])Find the RMS value. ...

Knowing the RMS value of a pulse waveform we can easily calculate the RMS value of a periodic square signal. The square wave in Figure 3 is a pulse signal with 50% duty-cycle. Its RMS value can be calculated from equation (5), where D = 1/2. Its RMS value is given in (11). F...
This periodic waveform is shown in Figure 1. It has a rise time from 0 to t1 and a fall time from t2 to t3. The plateau is between t1 and t2, and the signal is periodic with the period T. If you know this, then you can derive the RMS value of a triangle, square and pulse ...
For sine waves, the value is .707 X Peak Value; for non-sinusoidal waveforms, the EffectiveValue=RMS(Root Mean Square) Value. spellmanhv.com spellmanhv.com 正弦波波形时,其值 = 0.707*峰值; 非正弦波波形时,其有效值=峰值的均方根。
square wave. RMS Value of a Sinusoid Figure 3 shows the plot of a sinusoidally varying waveform, This sinusoid has an amplitude of A and a period of 2. If we wish to find the RMS value of this waveform, we repeat the steps we used to find the RMS value of the square wave. First...
number of samples, we’d have approximately the average value of that voltage, current, power, or whatever the waveform represents. The smaller the time intervals between samples, the more accurate the average will be. The mathematical operation of integration is a way to find what the value ...
RMS value refers to the square root of the mean square values of the voltage signal. Learn about RMS current and RMS value formulas.
