Noise: An Introduction
8
Probability Distribution
•The “distribution” of
the ‘noise” values
–Consider the
probability that at any time t the voltage is less than or equal to a particular value “v”
• The probabilities at some values are
easy
–P(-A) = 0
–P(A) = 1
–P(0) = ˝
•The actual equation
is: P(vn) = ˝ + (1/p)arcsin(vn/A)
