We address a more general version of a classic question in probability theory. Suppose X ∼ ${\bf N}_{{\bf p}}(\mu,\Sigma)$ (μ, Σ). What functions of X also have ...
Densities for the angle Θ = uX(mod 2π) and the cosine $Y = \cos(uX)$ can be expressed, through Fourier methods, in terms of the characteristic function of X. Thus ...
Three of the common filter topologies are Chebyshev, Butterworth, and Bessel. Which filter topology has the flatest response in the passband? Which filter topology has the steepest decline into the ...
