qiu_signals

Uniformly sampled axes and signals on them, for classical and quantum numerics.

integer_axis and physical_axis define the axes and their index orderings, signal the signals given by their samples, and algebraic_signal those given by a function or a SymPy expression; arithmetic holds the operators they share.

Modules:

• algebraic_signal –

  Signals given by an algebraic expression evaluated on a physical axis.

• arithmetic –

  Arithmetic operators shared by the signal classes.

• integer_axis –

  Uniformly sampled axes of integer indices.

• physical_axis –

  Uniformly sampled axes for position and its Fourier conjugate domains.

• signal –

  Signals given by their samples on a physical axis.
