  The relationship between a stable multivariable polynomial $p(z)$ and the
Fourier coefficients of its spectral density function $1/|p(z)|^2$, is further
investigated. In this paper we focus on the radial asymptotics of the Fourier
coefficients for a specific choice of a two variable polynomial. Hypergeometric
functions appear in the analysis, and new results are derived for these as
well.
