aspcol.kernelinterpolation.analytic_kernel_weighting_disc_2d(error_mic_pos, freq, reg_param, trunc_order, radius, c)

Analytic solution of the kernel interpolation weighting filter integral in the frequency domain for a disc in 2D. See definition in ‘Feedforward spatial active noise control based on kernel interpolation of sound field’ by Ito, Koyama, Ueno, Saruwatari.

Parameters:

• error_mic_pos (ndarray of shape (num_mics, spatial_dim))

• freq (float or ndarray of shape (num_freqs,))

• reg_param (float)

• trunc_order (int)

• radius (float)

• c (float)

Return type:

ndarray of shape (num_freqs, num_mics, num_mics)
