delay_signal(times, signal, dt)[source]

Delay a time signal by the specified amount

This function takes a signal and delays it by a specified amount of time that need not be an integer number of samples. It does this by adjusting the phaes of the signal’s FFT.

Parameters

  • times (np.ndarray) – A signal specifying the time values at which the samples in signal occur.

  • signal (np.ndarray) – A signal that is to be delayed (n_signals x len(times))

  • dt (float) – The amount of time to delay the signal

Returns

updated_signal – The time-shifted signal.

Return type

np.ndarray
