This image created with the
spectrum intercept algorithm
is based on the dynamical system expressed by,
where x' is the first derivative of x with respect to time, t, and x'' is the second derivative of x with respect to time.
The parameter values are, a=1, ω=0.2, b=-3, and μ=0.2
This image differs from the Noise image only in that the a parameter is 1 instead of 3. Driving the system less vigorously moderates the raggedness of the spectrum intercept image.
