What is interpolation and decimation explain with example?
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.
What do you understand by multi rate signal processing explain the decimation and interpolation process in brief?
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 interpolation in signal processing?
Interpolation is the process of increasing the sampling frequency of a signal to a higher sampling frequency that differs from the original frequency by an integer value. Interpolation also is known as up-sampling.
Is decimation and interpolation operations are linear?
From a digital signal processing point of view, both the pro- cesses of interpolation and decimation can be well formulated in terms of linear filtering operations.
