adding noise to a signal in python

Question

I want to add some random noise to some 100 bin signal that I am simulating in Python - to make it more realistic.

On a basic level, my first thought was to go bin b

Answer 1

You can generate a noise array, and add it to your signal

import numpy as np

noise = np.random.normal(0,1,100)

# 0 is the mean of the normal distribution you are choosing from
# 1 is the standard deviation of the normal distribution
# 100 is the number of elements you get in array noise
