Learn how to model multirate systems in Simulink^® using DSP System Toolbox™. Multirate systems can be found in a variety of different applications such as wireless, radar, audio, and consumer electronics.

A common challenge when downsampling or upsampling a signal is distortion. DSP System Toolbox provides a variety of multirate blocks that have built-in anti-aliasing and anti-imaging filters to prevent this distortion.

The DSP System toolbox can also be used to design and implement multirate multistage filters. Enter the filter specifications into the Filter Builder app, which then automatically determines the best algorithm for the desired filter response.
