WebA periodic sinusoidal voltage is constant and can be defined as V(t) = Vmax*cos (ωt) with a period of T. Then we can calculate the root-mean-square (rms) value of a sinusoidal voltage (V (t)) as: Integrating through with limits taken from 0 to 360 o or “T”, the period gives: Where: Vm is the peak or maximum value of the waveform. WebLTspice can perform .noise analysis of a circuit, where the noise voltage density (V/√ Hz) for 1Hz bandwidth) can easily be plotted for the output noise, input noise or for any noisy component like a resistor, diode or transistor. However, you can also easily integrate noise over a selected bandwidth in a .noise analysis. Figure 1.
