What is upsampling used for?

The purpose of Upsampling is to manipulate a signal in order to artificially increase the sampling rate.

What is upsampling method?

Upsampling or Oversampling refers to the technique to create artificial or duplicate data points or of the minority class sample to balance the class label. There are various oversampling techniques that can be used to create artificial data points.

What is downsampling with example?

(1) To make a digital audio signal smaller by lowering its sampling rate or sample size (bits per sample). Downsampling is done to decrease the bit rate when transmitting over a limited bandwidth or to convert to a more limited audio format. Contrast with upsample.

What is upsampling and down sampling?

Up-Sampling is a "Zero-Padding Procedure" that increase the number of samples of a DT signal. More specificals, when up sampling, zeros are added between the samples of a signal. Down-Sampling is to decrease the sample size.
