What is upsampling factor?

Upsampling by a factor of inserts zeros between every two samples of a discrete-time sequence. This expansion in time causes a contraction in frequency and the appearance of spurious spectral components, necessitating filtering after upsampling. The three sets of controls let you vary the path of the input sequence.

What is the purpose of upsampling?

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

What happens in upsampling?

Upsampling is the process of inserting zero-valued samples between original samples to increase the sampling rate. (This is sometimes called “zero-stuffing”.) This kind of upsampling adds undesired spectral images to the original signal, which are centered on multiples of the original 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.
