Filtering equation

There are various ways to characterize filters; for example: • A linear filter is a linear transformation of input samples; other filters are nonlinear. Linear filters satisfy the superposition principle, i.e. if an input is a weighted linear combination of different signals, the output is a similarly weighted linear combination of the corresponding output signals. • A causal filter uses only previous samples of the input or output signals; while a non-causal filte… WebMay 22, 2024 · The equations may in fact, describe a required filter's characteristics.

However, since it decays rapidly, it is often reasonable to truncate the filter window and implement the filter directly for narrow windows, in effect by using a simple rectangular window function. In other cases, the truncation may introduce significant errors. Better results can be achieved by instead using a different window function; see scale space implementation for details.WebMay 22, 2024 · The equations may in fact, describe a required filter's characteristics.
