What is the need of multirate processing give some examples of multirate digital systems?

Some applications of multirate signal processing are: Up-sampling, i.e., increasing the sampling frequency, before D/A conversion in order to relax the requirements of the analog lowpass antialiasing filter.

What is multirate signal 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.

What is multirate sampling in 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.

Which are the examples of multirate systems?

Multirate System

  • Filter Bank.
  • Field Programmable Gate Arrays.
  • Eigenvalues.
  • Real-Time Operating System.
  • Cyclostationary.
  • Sampling Interval.

What are the advantages and drawbacks of multirate digital signal processing?

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 advantages of multirate signal processing?

What is multirate in embedded systems?

Multirate embedded computing systems are very common, including automobile engines, printers, and cell phones. In all these systems, certain operations must be executed periodically, and each operation is executed at its own rate. Application Example 6.1 describes why automobile engines require multirate control.
