pyFDN.dss_to_impz

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

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:

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

• delays (ArrayLike) – Delay lengths in samples

• A (ndarray) – Delay state-space matrices (static, numeric only). For FDNs with absorption filters use dss_to_flamo.

• B (ndarray) – Delay state-space matrices (static, numeric only). For FDNs with absorption filters use dss_to_flamo.

• C (ndarray) – Delay state-space matrices (static, numeric only). For FDNs with absorption filters use dss_to_flamo.

• D (ndarray) – Delay state-space matrices (static, numeric only). For FDNs with absorption filters use dss_to_flamo.

Returns:

impulse_response – Shape [ir_len, num_outputs, num_inputs]

Return type:

ndarray
