DSP Blockset

Sample Time Offsets.   Simulink offers the ability to shift a signal's sample times by an arbitrary value, which is equivalent to shifting the signal's phase by a fractional sample period. However, sample-time offsets are rarely used in DSP systems, and blocks from the DSP Blockset do not support them.
