What do you understand by multi rate 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 the significance of multirate signal processing?
Multi-rate signal processing, an important part of the design of a digital frequency converter, is realized mainly based on interpolation and decimation, which match the sampling rate between the baseband and high-frequency processing side, especially in down conversion.
What is multi rate method?
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 the difference between interpolation and decimation?
Decimation and interpolation are the two basic building blocks in the multirate digital signal processing systems. The decimator is utilized to decrease the sampling rate and interpolator to increase the sampling rate.
