Is resampling the same as upsampling?

Resampling involves changing the frequency of your time series observations. Two types of resampling are: Upsampling: Where you increase the frequency of the samples, such as from minutes to seconds. Downsampling: Where you decrease the frequency of the samples, such as from days to months.

Is resampling the same as interpolation?

Resampling is used to either increase the sample rate (make the image larger) or decrease it (make the image smaller). Interpolation is the process of calculating values between sample points. So, if you resample an image you can use interpolation to do it.

resample Function

One resampling application is the conversion of digitized audio signals from one sample rate to another, such as from 48 kHz (the digital audio tape standard) to 44.1 kHz (the compact disc standard).
