What is the use of upsampling and downsampling?
Downsampling, which is also sometimes called decimation, reduces the sampling rate. Upsampling, or interpolation, increases the sampling rate. Before using these techniques you will need to be aware of the following.
What is upsampling used for?
The purpose of Upsampling is to manipulate a signal in order to artificially increase the sampling rate.
What is the benefit of downsampling?
It makes the data of a more manageable size. Reduces the dimensionality of the data thus enabling in faster processing of the data (image) Reducing the storage size of the data.
What is upsampling and downsampling in signal processing?
¯ downsampling (decimation) – subsampling a discrete signal. ¯ upsampling – introducing zeros between samples to create a longer. signal. ¯ aliasing – when sampling or downsampling, two signals have same. sampled representation but differ between sample locations.
