Implementation Details
The Noise Source generates wide bandwidth Gaussian-distributed white noise. Please see the example file electrical_noise_source.icp for more information on this element. The following figure shows the system in the example file:
The standard property "power spectral density" (PSD) defines the strength of the noise that distributed in the frequency domain. The following figures show the waveform and spectrum of the noise with the PSD equals 1e-17 W/Hz and 1e-16 W/Hz, respectively.
