Multirate-systems are systems that use data of more than one sample rate. They can be used to dramatically improve the performance by reducing data redundancy. Examples of such systems are sample-rate-converters and filter banks.
- Decimation, interpolation, noble identity
- Polyphase-filter and sample rate converters
- FIR-, IIR-filter banks
- Critically decimated- and over-sampled filter banks
- FFT-filter banks with windows und overlap-add/-save
