(n=128, g=5, gind=1, tb=4, d1=0.01, d2=0.01, phi=3.141592653589793, shift=32)[source]¶ 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)
