pyyeti.srs.lanroll

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

Increase sample rate using pyyeti.dsp.resample() for the SRS routine.

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

The pts parameter for the pyyeti.dsp.resample() is set to 65. This was determined from trial and error and comparison to the FFT method.
