Linear filters process time-varying input signals to produce output signals, subject to the constraint of linearity. This results from systems composed solely of components (or digital algorithms) classified as having a linear response.

Filter (signal processing)
linear or non-linear.time-invariant or time-variant, also known as shift invariance. ...causal or not-causal: A filter is non-causal if its present output depends on future input. ...analog or digital.discrete-time (sampled) or continuous-time.passive or active type of continuous-time filter.
