This example demonstrates the most simple usage of the Noise.UniformNoise block:

• globalSeed is the Noise.GlobalSeed block with default options (just dragged from sublibrary Noise).
• uniformNoise1 is an instance of Noise.UniformNoise with samplePeriod = 0.02 s and a Uniform distribution with limits y_min=-1, y_max=3.
• uniformNoise2 is identical to uniformNoise1 with the exception that useAutomaticLocalSeed=false and fixedLocalSeed=10.

At every 0.02 seconds a time event occurs and a uniform random number in the band between -1 ... 3 is drawn. This random number is held constant until the next sample instant. The result of a simulation is shown in the next diagram:
