I understand that you would want to reduce the amplitude of white noise as that of pink noise.
This can be done with the help of “Gain” block to scale down the amplitude.
You can follow the following steps:
- In Simulink, add a Gain block to your model.
- Set the gain value to 0.05. This will scale down the amplitude of your white noise from 1/-1 to 0.05/-0.05.
- Connect the output of your white noise generator to the input of the Gain block, and then connect the output of the Gain block to the step signal.
Below documentation provides info on “Gain” block
