pyFDN.dss_to_impz

pyFDN.dss_to_impz(delays, A, B, C, D, ir_len)

Compute MIMO impulse response from delay state-space (DSS) representation.

Runs one simulation per input channel (Dirac at t=0 on that channel only) and stacks the results into a single array.

Parameters:

• delays (ArrayLike) – Delay lengths in samples

• A (ArrayLike) – Delay state-space matrices (static, numeric only). For a complete pyFDN.FDNBuild with filter hooks, use pyFDN.build_to_impz().

• B (ArrayLike) – Delay state-space matrices (static, numeric only). For a complete pyFDN.FDNBuild with filter hooks, use pyFDN.build_to_impz().

• C (ArrayLike) – Delay state-space matrices (static, numeric only). For a complete pyFDN.FDNBuild with filter hooks, use pyFDN.build_to_impz().

• D (ArrayLike) – Delay state-space matrices (static, numeric only). For a complete pyFDN.FDNBuild with filter hooks, use pyFDN.build_to_impz().

• ir_len (int) – Length of impulse response in samples

Returns:

impulse_response – Shape [ir_len, num_outputs, num_inputs]

Return type:

ndarray
