To model a noise source in using this library, the u the block Noise.PRNG has to be selected. properly parametrizing this block is done on two levels: easy and advanced:

Easy Noise

Select a (Pseudo-) Sampling time for the block. This limits the bandwith of the block to 1/sampling time. A constant spectral density will be used. This type of noise will be good for standard sensor noise.

Advanced Noise

To select more advanced noise methods with a defined Probability Density Function to define the distribution of the generated random values, the "Advanced" Tab has to be selected. The user can select a wide range of distributions:

Furthermore the Power Spectral Density can be set to specify the frequency characteristics of the signal. Following methods are supplied:

Using the modular approach of the fuctions, it is possible for the user to develop and select their own kernals for specialized frequency responses.
