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)
