pyyeti.srs.linroll

pyyeti.srs.linroll(sig, sr, ppc, frq)

Increase sample rate using linear interpolation for srs().

Parameters:

• sig (ndarray) – The signal(s), time-steps x n.

• sr (scalar) – Sample rate.

• ppc (scalar) – Minimum points per cycle.

• frq (scalar) – Highest frequency of the SDOF system.

Returns:

• signew (ndarray) – The resampled version of sig that meets the ppc requirement.

• srnew (scalar) – The new sample rate.

Notes

Note that linear interpolation is not recommended for increasing sample rate.
