Click on a problem area listed below to read how it has been fixed.
Digital Filter Block Now Produces Correct Results for Complex, Cascaded, Second-Order, IIR Filters
Results of Digital Filter IIR DF1T and dfilt.df1t with Non-Zero Initial Conditions Are Now Consistent
SOS Coefficients of the Digital Filter Block Are Now Tunable
Source Blocks Support Data Type Override
Weighting Factor Parameter of Vector Quantizer Encoder Block Is Now Editable
Digital Filter Block Now Produces Correct Results for Complex, Cascaded, Second-Order, IIR Filters
Previously, the Digital Filter block output incorrect results when the SOS
coefficients were complex and the scale values were real. This
problem has been fixed.
Results of Digital Filter IIR DF1T and dfilt.df1t with Non-Zero Initial Conditions Are Now Consistent
If you are implementing an IIR DF1T structure with nonzero initial
conditions for the denominator states, the Digital Filter block from the
Signal Processing Blockset and the dfilt.df1t object from the Filter Design
Toolbox now produce the same results.
SOS Coefficients of the Digital Filter Block Are Now Tunable
The Digital Filter block's SOS coefficients are now tunable during
simulation.
Source Blocks Support Data Type Override
The Source blocks in the Signal Processing Blockset now fully support data
type override in the Fixed-Point Settings interface.
Weighting Factor Parameter of Vector Quantizer Encoder Block Is Now Editable
Previously, you could not change the Vector Quantizer Encoder block's
Weighting factor parameter. This problem has been fixed.
