symop.modes.transfer.rect_bandpass¶
Rectangular band-pass transfer function.
This module defines an ideal rectangular band-pass amplitude transfer.
The transfer is
\[\begin{split}H(\omega)
=
\begin{cases}
1, & |\omega-\omega_0|\le \Delta\omega/2 \\
0, & \text{otherwise}
\end{cases}.\end{split}\]
This models an idealized hard cutoff in the frequency domain.
Notes
This transfer is not compatible with the Gaussian-closed formalism and therefore falls back to numerical filtering.
