Fig. 3From: Spherical harmonic covariance and magnitude function encodings for beamformer designMixture and product of two K∞ kernels from Eqs. 23, 28. Weights w are fitted to X={12dB, −12dB} responses respectively at their centers of expansion (θ∗, ϕ∗). Only the magnitude responses are shown as the phase component is constant (0 radians)Back to article page
