The TimeSeries.resample function enables us to summarize/aggregate more granular data, based on a sampling interval and a sampling function.
Downsampling is a term that originates from digital signal processing and refers to the process of reducing the sampling rate of a signal. In the case of data, we use it to reduce the amount of data that we wish to process.
The opposite process is upsampling, which is used to increase the amount of data to be processed and requires interpolation to obtain the intermediate data points.
