There are various ways to characterize filters. The most common processing approach in the time or space domain is enhancement of the input signal through a method called filtering. However the digital data stream is first shaped with a gaussian filter before being applied to a frequency modulator.
Both terms are used by various authors to describe the entire process which includes lowpass filtering or just the part of the process that does not include filtering. In digital signal processing downsampling and decimation are terms associated with the process of resampling in a multi rate digital signal processing system.
