What is multi rate signal processing explain its advantages and disadvantages?

Potential advantages of multirate signal processing are reduced computational 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 is multi rate sampling?

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 processing?

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.

Why is multirate signal processing important?

Multi-rate processing finds use in signal processing systems where various sub-systems with differing sample or clock rates need to be interfaced together. At other times multi-rate processing is used to reduce computational overhead of a system.
