• dsp.VariableFractionalDelay

Multirate Filters

• dsp.FIRDecimator

• dsp.FIRInterpolator

• dsp.FIRRateConverter

• dsp.FarrowRateConverter

• dsp.CICDecimator

• dsp.CICInterpolator

• dsp.CICCompensationDecimator

• dsp.CICCompensationInterpolator

• dsp.FilterCascade

• dsp.DigitalDownConverter

• dsp.DigitalUpConverter

You can also model hardware behavior, and generate HDL code by using System objects or Simulink^® blocks from DSP HDL Toolbox™. These objects and blocks include hardware-friendly control signals and architecture options. To generate HDL code from DSP HDL Toolbox objects and blocks, you must also have the HDL Coder™ product. See HDL-Optimized Filters and Transforms (DSP HDL Toolbox). For an example that uses the dsphdl.BiquadFilter (DSP HDL Toolbox) object and generates code using HDL Coder tools, see Generate HDL Code for IIR Filter (DSP HDL Toolbox).
