Design a g-slider pulse b

Parameters:

  • n (int) – number of time points.

  • g (int) – number of sub-slices.

  • gind (int) – subslice index.

  • tb (int) – time bandwidth product.

  • d1 (float) – passband ripple level in :math:’M_0^{-1}’.

  • d2 (float) – stopband ripple level in :math:’M_0^{-1}’.

  • phi (float) – subslice phase.

  • shift (int) – n time points shift of pulse.

Returns:

SLR beta parameter.

Return type:

b (array)
