sample_from_piecewise_linear

qugradlab.pulses.sampling.sample_from_piecewise_linear(signal: ndarray[complex], fractional_indices: ndarray[float]) → Any

Samples from a piecewise linear signal.

Parameters:

• signal (NDArray[Shape[n_points, Any_Shape], complex]) – The piecewise linear signal to sample from

• fractional_indices (NDArray[Shape[n_sample_points], complex]) – Each entry will correspond to a sample. The integral part of each entry corresponds to the index i in the signal and the fractional part corresponds to the convex combination of the points at indices i and i+1.

Returns:

The sampled signal.

Return type:

NDArray[Shape[n_sample_points, signal.shape[1:]], complex]
