What is multi rate DSP?

Multirate simply means “multiple sampling rates”. A multirate DSP system uses multiple sampling rates within the system. Whenever a signal at one rate has to be used by a system that expects a different rate, the rate has to be increased or decreased, and some processing is required to do so.

What is multirate signal processing in DSP?

Multirate Signal Processing. • Definition: Signal processing which uses more than. one sampling rate to perform operations. • Upsampling increases the sampling rate. • Downsampling reduces the sampling rate.

What are the advantages of multirate DSP?

Potential advantages of multirate signal processing are reduced computa- tional work load, lower filter order, lower coefficient sensitivity and noise, and less stringent memory requirements. Disadvantages are more complex design, aliasing and imaging errors and a more complex algorithm.

What are the applications of multirate DSP explain briefly?

In multirate digital signal processing the sampling rate of a signal is changed in or- der to increase the efficiency of various signal processing operations. Decimation, or down-sampling, reduces the sampling rate, whereas expansion, or up-sampling, fol- lowed by interpolation increases the sampling rate.
