DSP System Toolbox™ software provides a collection of multirate filtering examples that illustrate typical applications of the multirate filtering blocks.
|Multirate Filtering Examples||Description||Command for Opening Examples in MATLAB®|
Audio Sample Rate Conversion
|Illustrates sample rate conversion of an audio signal from 22.050 kHz to 8 kHz using a multirate FIR rate conversion approach|
Sigma-Delta A/D Converter
|Illustrates analog-to-digital conversion using a sigma-delta algorithm implementation|
Wavelet Reconstruction and Noise Reduction
|Uses the Dyadic Analysis Filter Bank and Dyadic Synthesis Filter Bank blocks to show both the perfect reconstruction property of wavelets and an application for noise reduction|
